Very strange.. Never heard of this happening.
I haven't used Hardcore Darkness before but I can't imagine that's the problem.

Java Version?
CC Version?
MC Version?


Try installing a mod pack from the AT Launcher or the FTB Launcher that has CC, and check if you have the same problem.

I have experienced something similar in the past, except I crashed when I pressed certain keys.

The problem was that those keys were assigned to a certain mod's keybindings. I can't remember what mod though. Try looking through your keybindings and change those keys if you find them.

Happened to me as well on our server at some point, excaping to menu fixed it for me I believe.
Best of luck!
