Good morning.
Thanks for your help, love to understand how Necrovision's modding work.
It seems to be a script bug, it seems to be impossible to kill zimmerman during the first part of the fight and so, the game crashes. It's logical, we have to be under the ground, so if we kill him before, the game crashes because we are stuck on the first floor. It's not a problem, I can play, but playing with overpowered weapons is not advised for this fight.
@Csimbi : it's not your mod, it's normal don't worry
