I'm getting: Error in No particular event for object number -3:
Trying to retrieve width of unexisting sprite 2
when I try to run my 'game' [that was working totally fine before, I just went tried to clean up the sprite [it had nasty JPEG artifacts all over it], when I loaded the new sprite, no matter what, it wouldn't be transparent, and when I tried to make a new sprite resource, and have my object use that, this pops up upon running the game].
GM6 attached if it helps.
Did a defrag IDs, and it works now, but there's still the problem of the fact that the sprite has no transparency [the big one of Yotsuba, the green haired girl], despite that checkbox being marked.
Just noticed something else: everything looks very slightly rotated, by less than a degree.
