At the end of the Blanco industires map in Poisonville, it looks like there's supposed to be a cutscene that triggers when you walk up some stairs, but whenever I do that nothing happens leaving me effectively softlocked.

I've tried reloading the save and leaving the map and coming back, but same thing happens. I also verified the game's files, but all this did was reset my settings. Any ideas on what to do to fix this? I have MH's bugfix mod btw.
