Thought i'd experiment with creating 6 members via multiplayer mode

How can i save the game - i get a message "you cannot save at this time". I wasnt in combat. I had added imoen to my party and had dismissed a custom character.

How/when can i save?

Thanks

Hmmm? You should be able to save the game normally.

Either there was an area spell or some scripted thingy in progress (like when you give the golem the stone)... But this is also a bug, reloading (you should have an autosave right after Immy saves you) or moving to place that forces an autosave helps.
