Undo Breaking Texture

[eager spoke]

So I really don't know what is happening nor how to reproduce, all that I know is that sometimes whenever I press undo when dealing with my model it completely messes up the texture from my skin even tho I'm not even touching it

for the image I was working on the ear on the top right and then I pressed undo and it broke my entire skin

Also from checking it seems the UV is getting affected

(Result for "backups")
🖥️ The Desktop version of Blockbench (by default) creates backups of your projects every 10 minutes.
To access them, go to Help > Open Backup Folder, and search for your backup in the folder.
PS: The interval and how long old backups are kept can be changed in the Blockbench settings (File > Preference > Settings > Application).

📱 The mobile/web version (and the desktop app) saves a backup if the model wasn't saved properly before exiting the app.
You can access the backup on the start screen after reopening the app.

I know how to restore backups, I'm not too far into the project I just want to know if there is any way to not cause it cuz the UNDO function is very much essential, I can't just not use it for the entire thing specially cuz its much easier to texture the model first instead of making the texture then model, anyways, here's a clip showing what i mean https://youtu.be/hId7qyqQGZc

PS: Version 4.6.5 and I have no plugins installed either

the problem is that you somehow had a 64x project texture resolution, even though you use a 16x resolution texture

then when you undid the creation of the second 16x texture it reverted back to the 64x resolution, which isn't compatible with your 16x texture

... actually, it never reverts to the 64x project resolution in your video 🤔

or better said it only fixes itself once it goes back to that for some weird reason

that's kind of my problem, it shouldn't be touching my other texture

[lapis anvil]

it's not touching your texture

The texture is completely untouched
The UV has a stroke because of different project texture resolutions

(even though they are both 16x, so I don't know why it even started as 64x resolution)

actually, nvm, I'm mixing stuff up now 🤦‍♂️

let me rephrase that correctly:

you are using box-uv
you have 2 textures with different sizes (64x64 and 16x16)
when you undo/redo stuff it seems to set the working texture size to the one of the new one (16x16), so the program acts like your textures are 16x16, but the "old" elements seem to have UV values for a texture that is 64x64. So the moment those get updated due to undo/redo you see the visual change.

So there are 2 solutions afaik (that you can do for now). Either:
-Don't work with several textures
-Don't use box-uv
