I've come across something really strange when working on COTS.
I extracted some excellent head ani's from the Blue Planet mod/campaign. In BP, they were used to replace the standard set of Command heads. I jsut wanted extras. So I re-named them appropriately (head-cm6, a, b & c ; head-cm7a, b and c, etc..)
I noticed the following problems:
- They don't show up in the dropdown list in FRED (I assumed FRED looks up for a proper name and loads it), you have to use browse to select them
- They don't show up in game (tried in the few of the latest builds, including Chiefs')
