1. The Bastion
2. Eilantha, Rajasta, Tiriki, Thriorion (all characters)
3. Frequency is random. The game may last an hour, it may last one minute.
4. There appears to be absolutely no trigger. It happens when entering combat, when exiting combat, when opening the map, when opening a shop, when opening crew skills, or whenever my character breathes (I assume).
7. The game crashes to desktop without any error message(s).
