The bug also occurs when hovering over a usable quest item.
Yeah. It invokes the same thing as hovering over the map icon.
Due to the 1-2 seconds you get prior to the crash occurring, it is actually possible to complete the quest, it's just going to require 6 restarts of the game to do it, lol.
Quest items are in the Mission Items tab of your inventory. I've always used them from there (tbh, I never realized you could activate them from the quest log, d'oh).
