Hi,
today i wanted to date my server up to 1.2.3, i tried different versions of ModLoadMP and Forge but i always get the same Error on startup:
After the error nothing happens and the server doesn't start.
Display Spoiler
[SEVERE] Unexpected exception
java.lang.NullPointerException
at je.a(ServerConfigurationManager.java:117)
at wx.<init>(EntityTracker.java:27)
at net.minecraft.server.MinecraftServer.s(MinecraftServer.java:210)
at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:425)
at dm.run(SourceFile:490)
Does anyone have an idea what the problem could be?
