The boeotian helmet mesh is exported at the wrong position. In the actor it rests at the head prop point. If you change that to helmet prop point it's all screwed up.This isn't a problem for the gastraphetes who will never remove the helmet in a normal game, but if you want to use that mesh for other units/helmet actors, then the mesh will need to be scaled/repositioned. LUCKILY I ALREADY DID THAT FOR YOU. It was a btch getting this right because at first I didn't know what was happening when I saw it goofed up on the heads of other units.
Rename it to hele_boeotian so it doesn't overwrite the current hele_helmet_t
