When creating artboards, after reaching artboard num. 49 the next artboard and the one after that will both be number 51, skipping 50. When exporting all artboards as images, only one of the arboards labelled '51' will get exported.

This happens on both the latest Windows and MacOS versions of Illustrator.

When I created a new artboard (either by clicking the button or duplicating) after Artboard #39, #40 is always skipped.

The artboard numbering is broken. Screenshot shows how artboard numbers go 5, 6, 8, 8, 10, 10, 11, 12, 14, 14, 15 etc.

When creating new artboards in a new file it is skipping Artboard # 69, and instead creating two Artboard #70's instead. This is on Windows 10 Enterprise (22H2) with version 27.6.1 (64bit)

When I was duplicating a new artboard, the sequence number became 8 when the number of artboards reached 7. However, the sequence number remained 8 for the eighth artboard, and when I attempted to create a new document, it remained abnormal. The issue was resolved when I launched the official version of Illustrator. When exporting, there were missing artboards due to duplicate sequence numbers. After ten minutes, when I restarted Illustrator Beta, it displayed normally. The version of Illustrator I am using is 27.7 39 (64-bit).

Since Illustrator's last update (I'm using Illustrator 27.5), when I create more than 8 artboards, it skips artboard 8 and goes straight to artboard 9. So when I export all artboards as PNG, it skips artboard 8 because there are two artboards 9 and Illustrator only recognizes one of them.

(I'm using a Macbook with OS 11.7)

I have Illustrator v 27.5 on an iMac with macOS 13.3.1 (a)

I have a file here with 67 artboards in it. I am able to rename the artboards just fine as expected, but there appears to be an issue with the actual number illustrator has assigned to artboard 57.

There is no Artboard 57, and instead the number 58 appears twice.

Please see the attached screenshot - specifically in the pink circle.

The automatic numbering of artboards is not correct.
21 does not exist, while 22 exists two times.
Though when testing to save the specific artboards, the "first 22" saves as 21, therefore the underlaying logic is working.
Same problem with 25/26, 27/28, 29/30
This time I only tested until 30. I don't know if I've seen it before.

There is a bug when creating multiple artboards or adding multiple artboards; causing the numbering to be off.

Illustrator 27.4.1
Mac OsX Monterey 12.4

I automatically get 21, 22, 24, 24, 25…
instead of 21, 22, 23, 24, 25…
The artboard n23 is missing

Today I noticed that if this error started, it affects all other files too. Restarting Illustrator fixes it

Please don't mind this user with the hateful speech below. I think we all share this pain because of this problem, and understand the rage it often invokes. Comments like this are not pretty, but they are good signals. But please restrain yourself from calling people 'losers'.

You all losers think that adobe is going to fix this problem. This particular problem is glued in AI since 2019. They don't want to fix it. Wake up. We are all losers for paying this ''company''.

When I duplicate an artboard, it is duplicated with the same name as the previous one.

I have to change the name manually to export all the artboards otherwise it skips the duplicated artboards. When will it be fixed?

I may have find a way to replicate the bug : I just made two different files with large numbers of artboards, and I noticed that if I add artboards too fast, the bug happen. If I add some (with the "+" button) on a steady rythm, but not too fast, it doesn't occur.

When I copy artboards and make new artboards the automatic numbering of the artboards goes wrong. And when exporting an artboard you can't export the right artboard.

MacOS Ventura 13.0.1
Illustrator 26.5

When displaying a large number of artboards on the same screen, numbers don't follow (see screen capture, artboard 70 dos not appear, the 71 is doubled. When exporting by asrtboards, the first 71 does not get exported.

I created an A4 artboard then proceeded to add artboards in a side by side print layout but when I get to artboard 13, the next one added is 15 and the next after that is also 15, it then goes to 16? Very strange?

I have just experienced the same thing. and posted about it in forum and linked to this post as being similar. not causing me any real issues but I thought it might be useful to know that had same thing happen. I have been using Illustrator for 20+ years never noticed before.
