This is getting very aggravating. I am also experiencing this issue since 2.3. I'll hit the teleport button. Then all of a sudden my game will drop to 1-2 FPS, become unresponsive; And crash with an 'unexpected error' right there OR will teleport me after a bit, I'll seem fine, then 'unexpected error' crash me shortly after. It's happening every 3-4 hours, sometimes less if I'm teleporting a lot (hunts). Please fix this, as it's really starting to hampen my gameplay experience.
I also urge everyone to file a bug report with your PC specs, etc.
