Does someone know how to connect to the server if ur connection always got cancelled by the reason: "Internal Exception: io.netty.handler.codec.Decoder.Exception: java.io.IOException: Package was larger than i expected, found 34604 bytes extra whilst reading packet 48" ?
What was the last thing you've done on the server? Did you by any chance filled a chest with Storage Cells from AE2 and then grab the chest with a dolly?
Ender Chest from Ender Storage. The data will not be saved on you player file, it will be saved somewhere else.
