CTD on SPE terrain Mortain likely caused by ACRE compat

[aliasalpha]

I've started getting very repeatable crashes to desktop whenever I try to use Mortain in single or multiplayer. I got half a dozen people in my group to perform the same test and they all got the same results: any combination of ACRE and Mortain crashes the game. I'm not 100% certain who writes the terrain compats so I'm reporting to both sides just to be safe.

Error is:
