I am getting a FML world ID mismatch when connecting to my server using the recommended 436 and latest forge 438. Forge 435 works fine. The config is the same on the client and server (yes I have verified over and over). Message is as follows -
ID 4089 is mismatched. World: (ModID: Mystcraft, type vl, ordinal 3) Game (ModID: Mystcraft, type vl, ordinal 4)
ID 4090 is mismatched. World: (ModID: Mystcraft, type vl, ordinal 2) Game (ModID: Mystcraft, type vl, ordinal 3)
ID 4091 is mismatched. World: (ModID: Mystcraft, type vl, ordinal 1) Game (ModID: Mystcraft, type vl, ordinal 2)
ID 4092 is mismatched. World: (ModID: Mystcraft, type vl, ordinal 4) Game (ModID: Mystcraft, type vl, ordinal 1)
