Juro: Hi!

So, I've been quite thorough in this playthrough (done almost every side quest so far) and I finally reached Curst: I accepted the quest given by the bartender in the Outer Curst area and I'm trying to get all the pieces of the "key". However, when I get the quest to help the dump caretaker (Kyse), after speaking with him and getting to the inner area to talk to the thug there, I have a very big problem.

I get back to the outer Curst and get to the dump. As soon as the Nameless One is close to Kyse everythin stops (like when you enter in dialogue mode) but nothing else happens. I quickly went through a walkthrough and supposedly the thug I spoke earlier should appear and a fight should start. However, no matter how long I wait (up to half an hour) nothing happens and I'm stuck there. I tried loading previous savegames at different stages but to no avail. The same thing happens all the times. Anyone with the same problem that can help me out? I also got a feeling that this mission is along the main quest storyline, so I guess I can't progress in the game without completing it.

The game is modded with the widescreen mod and the Ghostdog Incredible UI.

Any help would be REALLY appreciated!
