It happens so often, when i'm scaling objects or when i'm painting them, i do something wrong, i press ctrl+z, and it undos a whole bunch of things, including actions i don't want to undo 

Also, after undoing scaling objects are in the wrong places, not original places 

Hey! Which version of Asset Forge are you using?

I'm using the newest version for windows and have the same bug.

I you scale an object then move it then press ctrl + z it will move back but also rescale back.

That also happen when texturing different blocks. Sometime it removes the texture from the last 2 blocks you modified.
