Most adventures and campaigns do not support the exporting of a character until after completing of the module -- if at all -- so you might just have to start a new module and character(s).

Why this needs to happen is that some dungeons are designed without an exit point making them impossible to leave. This appears intentional sometimes. Also, there are some dungeons without resting points. The last dungeon had no resting point and my characters started with zero spell points. The ability to exit at the same level you started with no extra loot should be implemented. The no exit and no resting point problems have happened in at least 3 instances with dungeons. The character progression effectively is lost if it is mid level dungeon.

I really have to agree here. Why do I have to sacrifice my favourite characters just because I start a bugged campaign or one not to my taste? There ought to be a way to quit it and lose all progress.

Hey there, this is to report to the creators directly, so that we can place a way out. Then you can load from disk and exit.
