Just ran into NPC in the outskirts of a large city. He talked to me and engaged a bunch of zeds with his Savage (no silencer, i supose, so guess, what hapen). After he fire like 10 shots at the horde game freezed, and debug.log states C:\Users\jenny\Desktop\cygwin\home\Kyratzes\Cataclysm-DDA\npcmove.cpp[321]: NPC didn’t use its moves. Action 17. Turning on debug mode.
If anyone interested, just say what else info i can provide.
P.S> Screenshot shows what became of that NPC just when the bug happened. Those ` and = in top left corner.
