I teleported to a plot and immediately after i spawned i was kicked from the server. Now every time i try to logging to Creative i am been kicked from the server and this message pops up: Connection Lost Internal Exception: io.netty.handler.codec.DecoderException: java.lang.RuntimeException: Tried to read NBT tag that was too big: 2098070bytes where max allowed: 2097152
Have you tried restarting your WiFi or at least your Minecraft? Since this always seems to be the case. I would put this under bug issues if there's nothing to fix it.
I no longer have the same connection i used to when that happened and i have reseted my computer (for unrelated reasons) so my game client is not the cause.I'm pretty sure its related to the plot having an abnormal amount of items spawned or something similar. I might put it at the bug issues but i don't think its directly a problem of the server it seems more like its related to the plot-owner and something he did.
Bought the Teleport to Spawn from the shop and i can play again (don't know why i didn't think about that :P)
