Document has 42 artboards in total and there are two sets with duplicate numbers I can't change. Very frustrating to see how long people have been flagging this for with no fix. It has messed up my exporting of logo files and meant I almost sent the wrong ones to a client!

This is still not fixed in 25.3.1 Very frustrating.

If i create a file with 50 artboards, numbering of 24 & 32 comes twice
& illustrator creates 50 artboards
it wont create page no. 22 & 31

Design on these duplicate artboards, are non exportable in JPEG format

アートボードの名称をきちんと連番にしないと画像等に書き出した際、めちゃくちゃな順番になってしまうのと、ファイル名も～のコピーのようなバカみたいな名前になるのが困るので、アートボードを一斉に連番でリネームできるようにしてほしい。

Here's a very simple test file. One current artboard, no layers, no objects in the file.
Draw a single rectangle, and convert it to an artboard. Instead of artboard #2, it will be #3.
Create another one and it will also be #3. If you create a 3rd one it will be #4.

画板有两个编号为39的 并无法导出其中一个。
画板37后新建直接为39 没有画板38。

When I create a document with 3 or more artboards it numbers the 3rd artboard as number 4, but it also numbers the 4th artboard as 4, so when exported to JPGs it doesn't save the 3rd one.

Reset illustrator preferences. Here is the navigation: Illustrator > Preferences > General > Reset Preferences. Press and hold Option+Command+Shift as you start Illustrator. There we go!

Have a report that it is not fixed in 25.2.3

Hi, I'm having a recurring bug on illustrator when I have a large amount of artboards. What happens is that illustrator will skip an dartboard number and duplicate another, for example (73, 75, 75, see attachment) That way when I export I end up missing an artbord file because illustrator only exported one of the 75s artboards. See in this case I have two artboard 67s, two 76s and no 74. This happens quite often as soon as I pass the 20ish mark of artboards in a file

same

Here is what I see

I am working with a large number of artboards in a single file. 61 to be exact. The software has named artboard 52 twice. Two different artboards. 51 is missing.

I have tried to upload an image in jpg and gif and your system is rejecting it.

I downloaded the latest update for illustrator and there is still an artboard error in numbering. I was hoping it wouldn't have been a problem till I exported each artboard as a PNG and I was missing art. Trying to create 60 artboards. If I copy and paste artboards I still have the same issue starting at artboard 23 then 25 then...

same here.

Same issue and doesn't export the first of the duplicate artboards!

When adding additional artboards to a document, artboard #43 becomes #44 (you'll end up with two #44), and Illustrator skips #46 (go from #45 to #47).
