RE: geometry change when opening old assets. Adric wasn’t able to reproduce except with shrink wrapped sprites, which change their geometry if you edit a sprite that uses it due to a more conservative algorithm being used starting in 4.8, but fully custom and source/tight rectangles both seemed to load OK and not change when you edit them. If you’re seeing on other kinds of sprites, I’d appreciate a repro when you get a chance.
Cheers,
