Detailed description of the bug and pictures if applicable:
When I try to complete quest I keep getting "NullPointerException" and the game freezes/crashes.
It doesn't actually crashes so there's no crash log but here is the Game Output up until "crash"

This is what it looks like when it does the freezing:

Ways to reproduce the bug: Just complete some quest.
If needed I could add the questlines too.

I guessed this would happen at some point in time. If you have a small vanilla line to share that would be nice.

Hmm sounds like what I experienced a while ago and for which I fixed the networking issues in the messages. Are there other spots in HQM where there is this kind of thread related stuff going on perhaps?

Here's a part of the questline: http://pastebin.com/u032Di2G
If needed I could paste the whole one too.
And I don't think there is other stuff like that, or at least I haven't noticed.
