Loading Minions from NBT causing server to Crash

[alexvirital]

Good morning!

Got AOTBT running on my server this evening with some success until I ran into a very weird bug...

I'm running my MC server on a Ubuntu 12.04 LTS vm, and was watching as each time I attempted to log in, it started throwing the following into the logs:

2014-02-04 01:38:25 [sEVERE] [Minecraft-Server] Reached end of stream for /ip address

This persists even if I remove the alexvirital.dat file from the /world directory. Anotherplayer is an actual user on the system, who was not connected during this attempt. it seems as though it's attempting to assign my minions to him, or his to mine, or in some way the streams are being crossed.

Is there a way to purge minion data from the server without totally nuking the world?

[Jaxon.Wyatt]

Minions are a bug on the server ATM, you will need to disable the mod until the bug is fixed.

[Jaxon.Wyatt]

Is it ok if i could have the IP? i will help from there on

[alexvirital]

Interesting. Didn't realize minions was broken. Just removing the .zip from the mods folder on the server and bouncing minecraft should take care of that, yeah?
