Version: 1.8.9
Replaymod: v2.2.0 b4 (and b7, tested both)
It seems like randompatches and replaymod don't sit well together :P. Asm code caused a crash on startup (before other mods could be loaded)

Have you made sure this is actually RandomPatches and not any other of your coremods?
If so, report it to RandomPatches, they're violating coremod contracts by causing some class to be loaded prematurely.
