Game crashing 'randomly'.

nuh5000

So far it's happened a dozen or so times. I can't pinpoint any single cause, at least something that I am doing.
Last occurrence, was when I was standing idle in protectors enclave.

This was the most recent error message, I will update with others if they differ.

ERROR: Unrecognized command "(null)" (did you mean "-(null)"?)
Line: utils\cmdparse.c(2802)

Has happened some more. All with the same error message.
Last one, I was AFK. So it definitely isn't something that I am doing.
