Zmod is so broke that if you undo something it deletes a object from the hierarchy. This is why Zmod 2 was pirated so much because it was also broke. We have to pay a subscription for Zmod 3. I'd be fine paying a full price to have it forever but noooooooo a subscription for a program that can't even keep what was done in the memory, has random memory errors, says I can't import with multiple ZMod windows because "mEh lIcEnSe doN't aLow dIs" even though there are no other licences?, & etc. It's annoying. Good shit for over a decade of developing but at least it works.
After posting this and switching to another save. "I should also add random fucking freezes or loading for no fucking reason that for some fuckin' reason the scroll bar on the right of the material editor is used as a loading bar"
