I have installed the 4.2 patch and I have encountered few problems with it.
It's been some time since I have played Hellgate London and it was with the last 15b2 patch, maybe I don't remember some things correctly.
These are some problems I have while I am playing the 4.2 patch:
- the enemies i kill, often hovers a few feet in the air after dying, i didn't remember it beeing like this in the vanilla game
- the autotracking of quests doesn't seem to work, I have to manually click them in the list
- when I abandon a quest, no NPC gives me the quest again ( for example abandoning the main quest line, searching for the rift in the British Museum )
