I'm having problems with using Railcraft on my server. Whenever I try to connect to the server, the Dirt background with the "done" button at the button. Pressing it returns me to the game's main menu. No error log is generated when this occurs. No other mods or coremods are installed when testing.

The server appears to run normally. Nobody is able to log on to it when the mod is loaded by the server.

Tried with a newly generated world with the same results.

I tried a with a fresh server .jar and a fresh client .jar with the same results.

Loading other mods by themselves works (Builcraft 3, IC2, RP2, ExtraBiomesXL, NEI, Thaumcraft).

This is using Railcraft 6.13.1.0 with MC 1.4.6 and MCforge 6.5.0.489

Also tried with 6.12.2.0 with the exact same results.

The mod works perfectly in single player, even with other mods.

Also note that I'm having the exact same issue with Forestry and IC2 Nuclear control.

there is a "mismatch error" near the end of the FML log.

Error on line 88 of the FML log:
