I got to the final battle. I walked in the normal way, had a brief conversation with Bishop Alexander, and then it
said the battle started, and everyone seems ready for it, but... nobody's doing anything. The turn indicator seems to indicate that it's Ifan Ben-Mezd's turn, but I can't make him do anything. I can quicksave, though. Here's my savegame. I don't know how useful it will be since I can't reproduce the issue from before walking in.
http://darkseam.com/QuickSave_3.zipI'm not looking for a solution for me. I already reloaded an earlier save and just went through the ~2 minutes of stuff I lost and went back in (didn't run into the problem the 2nd time). I'm just posting this here in case the devs can get some sort of useful information from the savegame as to why nothing's going on, despite it probably missing the most important piece of the puzzle.
Note: I have tried restarting the game, but no matter how I load the linked savegame, it's the same result.
