Board Thread:Bug Reports/@comment-67.168.8.210-20141230032745

I can run my lotr server just fine with the older versions of the mod but when I got to 21.3 the I get this message in my minecraft.

Internal Excepiton: io.netty.handler.codec.DecoderExeption:Java.lang.IndexOutOfBoundsException: readerIndex(11) + length(102982) exceeds wrighterIndex(37366): UnpooledHeapByteBuf(ridx: 11, widx: 37366, cap: 37366)

and in the server window it says

[15:31:54] [User Authenticator #2/INFO] [net.minecraft.server.network.NetHandlerLoginServer]: UUID of player LuckySilverStar is 836b6bbd-f9f9-437b-bd26-6b078baf0c50
