When you toggle lefty mode, upon death it will be switched back to righty, despite what it says in the options menu.

What I expected:
To continue being a lefty after death

What Really Happened:
I was switched back to a righty

Possible In-Game Fixes:
-Relogging works just fine, however it's pretty inconvenient to have to relog every time you die.
-Switching back to lefty in the options menu is another option
