This is a known issue affecting Mac users.
Steps to Reproduce
- Load up a Torchlight character under Mac OS X.
- Allow your character to be killed during gameplay.
- You should get a dialog presenting a list of resurrection choices. Ignore it and quit the game using Cmd+Q.
- Relaunch the game. Your character should be accessible now.
We are unable to repair your character save. For now, our recommendation is to avoid using Cmd+Q to exit the game while the resurrection dialog is displayed.
