Illustrator 29.7.1 on Mac Ventura 13.5.2 (22G91)

I dont' know whether it's related to this current issue, but now I have parts of my text that change appearance when I'm trying to change the Font weight of another part, or when I try to type more text.

The workaround I have found it copy-pasting the text into a new Textbox. But still, this needs to be fixed.

Still the same problem with the 29.7.1 version....

29.7 solved this issue for me.

I previously reported that the issue was not resolved in version 29.7, but this was my mistake (I was looking at a file that had been saved with the fonts already replaced). The problem has actually been resolved in version 29.7. I have already deleted the incorrect bug report I submitted earlier. Thank you to the development team for your efforts.

It just happened to me too (Illustrator 29.6.1 on Mac 13.5.2).

It happened only to the fonts I had replaced with the Find/Replace Fonts… tool. The others were OK.

I cannot find a way to replicate it, but there seems to be a bug that occurs randomly where Illustrator doesn't save the font selection on the document correctly. When re-opening properly saved files that are affected, the file will open, but the majority of text in the document having the incorrect fonts applied. In a production environment, this is extremely frustrating. This needs to be addressed immediately. I cannot post any examples as the examples have occurred on artwork for a company I work for, however, this bug has occurred on two separate occasions, and it is frustrating to have to redo work that has already been done.

I have the same issue with 29.6.1.
This is a big issue. In my case, it seemed to have correlated with 29.6.1 update.
Can we get advice on which version to downgrade to and an ETA for the solve?

I can't install the beta version right now so I can't test this, but i have a question: this fix corrects previously messed up files, or the fix only prevents this happening to other files?

If the Dev team changed the indexing method for the fonts, would be simple to solve it making a conversion for the tables of older files.

I have updated and am still having major issues. I have noticed that for some reason it keeps trying to use this font - which is not one that I have installed on my computer and one that I have never installed in the past. PlicataPERSONALUSEONLY

I did some tests and version 29.7 doesn't seem to have the problem.

This is a critical problem that I've never experienced until recently in Illustrator. It's not that the fonts aren't recognised, it ACTUALLY CHANGES the font in the document!! Adobe, please fix this!!

I’m experiencing an issue with Adobe Illustrator version 29.6.1 when working in a team on a shared server. Specifically, when a colleague saves a file from their computer and I open it afterward, the fonts are not displayed correctly:

some fonts are replaced with others

in some cases, the entire text box disappears

the issue seems to occur mainly with Myriad Pro and Myriad Variable Concept fonts

It’s possible that the problem is related to shared font management or system incompatibility. Has anyone encountered the same issue or has any suggestions on how to resolve it?

Well I cancelled my subscription, was waived my cancellation fee, and I'll be charging my credit card back for the last year that I already paid for. This ordeal "inspired me" to go back to my roots and figure out how to pirate software. Now I have free copies of older versions of the software which work fantastically, and I also learned how to properly emulate a fake CC subscription, so I mean I can just use current versions if I want, too.

I spent literally months struggling to find workarounds for bugs and glitches when I could have just spent 35 minutes on Google.

Good going, ********. Lol

This absolutely unhinged issue is beyond frustrating - it's been happening for me all week since an update. To find that this is a known issue that has been happening for others for MONTHS.... Adobe. DO. BETTER.
I'm hoping reverting back to v29.4 solves the issue but not holding my breath.

Happened to me today. I've been working on one single project off and on for the past few months, a business card for my new small business, and it's all gone in a flash.
I even went out and licensed a font. Now my whole project changed in ways I don't remember how to correct.
It feels like months of money, time and fulfillment taken from me.

Edit: I fixed it but **** this **** fr

Having the same problem, on multiple files, but not ALL files on our server. Some fonts changes weight, some fonts change to other fonts currently being used on the same file, doesn't look like there is any logic.

We have +10 people working on several projects (not 2 people working on the same files at any time), but each project may have a few files with this problem. If it's any relevant, we use OneDrive to share files within the company, and most of us were on Illustrator 29.6.1. Reverting to 29.4 DID NOT solved our problem.

It's been two months now, with more than one update since then.

Is there a way to recover the files that this glitched ruined? I saved my .ai file, closed out adobe because it was lagging, re-opened adobe and my .ai file within 5 minutes and all the text was mixed up with different weights and fonts. This is a 10+ hour project that has a tight deadline.

Is there an update on this? I am also experiencing this and it is extremely critical as I open and close many documents daily for work. It has caused a lot of wasted time. For a very expensive program, I would have expected this to be an important fix as it has been almost 2 months since this post.
