If a mod breaks co-op, restoring these two files reverts you to pure v1.4.16.0 without re-downloading.

Specifically, this build addressed a notorious crash bug associated with the "Vortex" spell in PvP arenas. Before this patch, casting a Vortex in a specific sequence could cause the server to crash, forcing a draw. V1.4.16.0 solidified the netcode to prevent this, ensuring that matches were decided by skill (and a little bit of lag) rather than who could crash the game first.
