As I had guessed, the owl event with outdated files made you crash.
To update your data folder (until Tiara updates, if you like), get this one: Its my data folder. It contains most everything...
I try to keep an functional data folder at mediafire.com/lostmage333 all the time. If you have data folder problems, check that. If it doesn't work, message me in game (or email@

) and I'll update it.
Files were updated using winmerge. If I missed anything, let me know.
Enjoy
