Had a bit time on the afternoon so this is the second AI freezing the battle recreation as reported by steam users:
http://steamcommunity.com/app/545600/discussions/1/1693785035818232948

This time it's a churcher trying to throw a grenade situation:

Used the same map as on awg's picture, DowntownMed4.
In this setup, according to the log he was aiming a tile where Emilia is standing on the picture.

It ends with the same as noted by awg, "Can't throw this far".
What visibly happened is that he switched from smg to grenade and turned. Then he freezes, not even any idle movement. This AI hanging seems happen a bit later than in other cases, i.e. he managed to do some actions.

Daithi:
Thanks, I'm going to tackle this one soon. Will review code to figure out how invalid orders are getting through and set up a test scenario where eveyone gets grenades to test fixed.

ushas:
Heh, adding nothing new on top of what was already reported. Sounds like a fun. Good luck with that!
In this case, fire is indeed suspicious element. However, the churcher had no problem to go through fire and switch to smg to shoot at one of us on a turn before that. It hangs after he changes to grenade.

I'll try catch (well, 'try' as far as luck goes) if there are other situations, in case it might help to narrow things down for you.
Were there any other AI hanging reports? Those screens help a lot.

Daithi:
Trying to untangle this now. Hard to call on the fire - it could well be a factor. Another possibility: does the character ever move before the throw when the game hangs on an AI throw? In the recent examples I've seen, I don't think they have.

Daithi:
Many debug statements later: looks like a logic error which is more likely to occur when fire is present. Now to test...
