In order to fix the replacement bug, and while we wait for a comprehensive patch including both a new executable and updated data:
Go To
<game path>\EAW\GameData\Models
Delete
Models.Cached
The next time the game will run, it will probably need up to 5 extra minutes. This will rebuild the cache with corrected data. It should fixes the bug about replacements not being used.
Cheers and have a nice Christmas all
