Hi,
So I've got a project with a number of sprite collections, one of which has two materials configured. Around half the sprites were configured to use one, the rest the other. After upgrading to 2DTK 2.3 (from 2.2 I think), however, I found that all of the sprites defaulted back to using the first material. Both materials are still listed in the sprite collection's settings.
So, I tried manually correcting them (not so tough). On changing the material for each sprite the "Material" label turns blue. But when I hit "Commit", everything just reverts to the first material again.
This seems like a bug to me, but I'm wondering if I'm missing something. Has anyone else had a similar issue?
