Missing Animation?

[BlackVegetable]

I cannot recall the exact error message but while fighting (and nearly finishing off) a group of Ents, right as they bashed their way through a stone wall I formed I got an error claiming it couldn't load a missing animation. This then shut the program down. Has anyone else encountered this problem? This was my first crash.

(Running Windows XP, if that makes a difference.)

yes, same crash has happened to me also. only in magic valley though.
i did then something else for some time and went back to try again and
then no crash.

i'm running vista sp1.

Interesting, that's the same location I crashed in. . .
