I'm just playing the game a few more times to see the frequency of some bugs and help oyu out ^^ haven't encountered that one Bear trap bug except one time and it worked for a very specific bear trap and I could reclaim only that one.
Wrench throw has become one of my favorite abilities to be honest, especially early on against the villagers who place bear traps! I never expected it to be so good! it even helped me stunlock one (and sometimes two, if you get lucking with pep-pill's extra turns) of the Mayor when I fought him for fun! The gun equipping bug did not happen on my third playthrough. I will play a couple of more times to see if anythin happens again or something new comes up!
