• Fix Auto update UVs reenabling after each pack

This is not actually a bug, i feel like it would cause more confusion because you need to have uvs update automatically most of the time, so the scene can load uvs when its loaded in editor. Ideally there shouldnt even be the auto update UVs toggle, it would just work

Yeah I see, maybe it could be enabled by default and kept disabled if the user manually disables it?
