Pabazu: Right, so now a new problem has sprung up. I've acquired the Oscillation Overthruster, but now I can't leave the Lincoln. When I click the exit it states that all have to wear their swimsuit, and they are - have even tried clicking all 4 suits off and back on to the characters to no avail. Any help would be appreciated.
Is it possible they have anything equipped while the swimsuits are on? You're not supposed to be able to wear them if you have anything equipped, but sometimes a bug may crop up allowing you to do so.
Alternatively, what about transportation spells? And if worse comes to worst, you can just sit and wait to die; you'll respawn in Harmondale with no gold, but you won't lose anything else (including game progress). If you have guardian angel and keep it cast, you won't lose any money either. And it won't be canceled if you rest without healing (edit: it will last as long as it is cast for, so if it's cast for less than an hour, resting on hour will lose the spell, but not resting five minutes), so you won't have to sit around in the real world that long either. Your characters will mostly die around midnight I think, so that's when you want to have guardian angel cast.
