I've been coming across several quest bugs, so I decided to list the ones I know of, if you know of any others, please add them so I might compile a list and maybe we can get a final patch.
1. Trevor in the Merchant Guild, if you get the quest about Tingalf before solving the quest for Marcus involving Tingalf and his suppliers, the quest is bugged.
2. If you're trying to get the wine from Anthrabert for Corinna the Summoner and decide not to blow up Mpenzak's wagon and just go to his room to get the wine after you've told the guard to arrest him, the quest is bugged.
3. In Stormfist castle, you can pretty much pick up every bottle of ale and beer in the castle and you still might not get to complete the quest, which leads you to fail the quest once you've been thrown out.
You may not care if you can't complete them, but I find it very unprofessional of a developer to leave these obvious marrings on a game, it doesn't exactly make me want to buy Riftrunner... <img src="/ubbthreads/images/graemlins/devil.gif" alt="" />
