Quests still very buggy

I am enjoyingthe latest build very much, thanks for the work to date. I just wanted to report that I am still finding quests to be quite buggy. A few examples below, excuse the vagueness on some - can't remember their names.

• Sagog's Egg quest - still have issues completeing it, won the fight, got a message about finding the egg but it didn't show up in inventory. Went back to Sagog's lair - no result.
• One of the armor quests I did twice as an experiement - first time I won the fight and lost half my army in the process, no sign of the armor. Reloaded, did fight again, won without any losses - got the armor.
• The one where you read something on a wall and have to visit a newly spawned location. When I visited the location it dissappeared but no quest dialogue came up and the quest did not advance.

So in general I am finding quests to be very buggy. Results seem to vary from game to game and sometimes exiting and reloading just before completeing a quest can help them along. Just seems the whole quest scripting is pretty fragile and all sorts of other odd factors can affect their reliability.

Anyone else having quest issues?
