Deine Mutter Good to know your using Fragmotion. So when your saying you "Merged" the two
entities into one, your still using "two" textures maps, correct ??? If so, they probably look fine in Fragmotion.
So go into the new entities .fpe file. Remove anything on the "texture=" line. Just leave it blank and test again.
Also make sure your entity is dynamic ( not static) Entities must be dynamic when using more than one texture.
My games never have bugs. They just develop random features..
Lots and lots of random features...
