Quest Bugs after Patch

[jayarcher]

I updated game through Steam. After that I had to repair with the repair tool to get all my saved games. Now im at Mehgar, in order to talk to Cief engineer Debat.
First I could not talk with him at all only see what he had to sell. I used the repair tool again and started up and was able to talk to him. After that I guess im supposed to take the train back to the mines and go for demons. BUT the train cannot be activated.... So should I take the train back ? I can see no other options... and if so, how do I do it?

Since last patch quests have been ******* up regularly... Also the wayward book was ***** up. I could not hand it in to the necromancer...

Sigh how can they release such a buggy patch.

Best Regards,
