I was stuck with my character in the fight with The Lambach after I used the skill "Wings of Ishmir". After I would use the skill I was able to use everything but I couldn't move at all. Not a roll, nothing. Only another jump with that skill could free me.

The second bug I encountered was a disconnect from the server (at 0 am, so it could be something else) when I transitioned into chapter 3.

One last thing: The spoken dialog at the end of chapter 2 between Gernese and Valeria did not match the written dialog, at one point. It just threw me of for a second. So, just something to keep in mind when more important issues are settled ;-)
