There's a bug when i go to that morizou place in kikaigahara and now ongiri stops responding each time i load my char there....please someone know how to fix this without uninstalling because i don't to want to wait 6 hours just to play again and figure out the bug is still there...

Re-installing might help but there's no guarantee that it'll prevent you from crashing a few seconds later after logging in or somewhere else, for example in the Oosumi Plains, that's what happened to me. Everyone else suggests to update drivers/software/.NET/Windows/etc. but it's also not the cure for this annoying bug.
