While flying over the mountains using the air shard, I apparently ran into non-existent beings. Any directional movement caused the game to produce an error, except moving down, which triggered an encounter with orcs. However, it then produced an error before transferring to the encounter screen, leaving me sitting in the wilderness. Continuing was possible, but returned to the same issue. Saving likewise could be done, but it returned upon loading. I probably should have included the save file, but aborted.

"A controlled JADE error occurred.
Please see the stack trace for details.
