.assumecombatstance won't work

[AronFF]

Issue Description:

While I can choose a fighter kit, and choosing dervish goes through without an issue, giving me passive bonuses like a reflex save bonus and ambidexterity, I can't use the fighter stance due to the command not working.
It says that the DMFI command is either nonexistent or restricted to DM's.

I'm closing this because every class kit will be re-worked from ground up.
