I sent you an email, but in case it didn't reach you: the Deep Quagmire of Abyss breaks if you do the Alchemist mandrake quest there. After you do the quest, the option to explore stops responding.
And when uninstalling the game, I got this error:
I tried uninstalling with Revo and it missed the updater and my save files, and who knows what else in who knows where. I'm feeling tempted to reformat and clean install, lol.
