I'm pretty sure that's Kimera's fault. You might think I would have tested if field animations written by Kimera actually worked fine in game right? Well, guess what, I didn't. I didn't do so because I just need the thing working on a custom game engine I wrote 3 years ago, and it worked. Soooo... well, sorry. For some reason I never heard it wasn't working. I'll fix the bug soon.
Meanwhile you can use the original animation file.
