sprite skinning lost on device

Hello,

we have problems with sprite skinning getting lost on devices, both for ios and android. For all team members, win and mac skinning is showing correctly in the editor, including our build machine.

The curious thing is that it did work before. Because of a misunderstanding the 2d animation package was removed once, obviously breaking as the sprite skin component was missing now.

After adding it back, everything was back to normal in the editor, just on device the problem remained.

We tried pretty much everything, deleting library on the build machine, tweaking skinning, re-importing the sprites with no avail. Is there any other caching I'm not aware of?

This is sadly hard to reproduce in a simple project but I'm simply wondering if anybody else has come across something similar by any chance?

Thanks all in advance,
seb
