Where are you seeing these errors? I don't know a whole lot about sprites and the like, but would like to resolve this issue if possible. Though I don't see it causing any problems other than the listed errors in a log I assume?

Does not effect game play, just seen them in the log file, when other mods crashed.

I will try to work out the cause of the problem. Thanks for the heads up.

Issue should be resolved now. Thanks again for the heads up and I apologize it took so long.
