Insert creature is causing the problem. Need to look up the creature in the cell in the CS and then look it up in nifskope to see if there is anything unusual about it.
EDIT: Linking the skeleton is causing the problem. I got rid of this problem long ago for what I thought was all creatures. Apparently the method I use does not work for some creatures.
This problem should be fixed with my latest commit, at least it seems so in my tests (on animation2). The heart is a bit different in the way it is setup than normal creatures, and it had 277 records! Right now when we animate the heart it doesn't really do much since we don't support particle effects and other things.
Dagoth Ur looks cool though.
Sorry, there is no way I will go through all this conflict resolution again. The animation2 branch is hopelessly outdated. Since you had some commit problems anyway, would you mind redoing it? (create a new branch based on master).
Merged in master, kept animation.cpp the same since there are so many changes that were never integrated into master.
When you open up a gui window animations keep on going. I had it set up before so it would stop when a gui window is open since this is what morrowind does. Why was this changed?
