Reinstal bfme 2 and rotwk i had the same problem.
Hey guys.
How odd!
I've only just had the chance to come online and see this, but I rinstalled ROTWK and it kinda didn't work, so I reinstalled both BFME2 and ROTWK and it's worked perfectly.
Silly bug
Still, it looks great again now, no problems at all and best of all my mod's intact.
Stil no further on the permanently killed by thing though lol.
Maybe for now it's just best I remove the references in that line of code for the 2 or 3 heroes I've added it in.
