Hello, and thanks for your report. This is a known issue reported on forum posts 1267, 1269 and 1284, affecting some particular servers. Currently, I don't know what's causing this and a quick investigation (1274) did not allowed me to find it out. So if you could provide more details about the server you are joining it would be helpful. Thanks!

my server is with bungeecord and spigot 1.8.6, when i put /server factions always crash

I don't think the program supports 1.8.6 just yet. It can probably connect to your Bungee instance because the server's version is within limits, but when I try connecting to 1.8.6 servers, I get a stacktrace and the program exits.

Seems highly probable, but after taking a look at changes on http://wiki.vg/Protocol there does not seems to have changes affecting MCC related to 1.8.6. Still investigating...

[ORelio]

The issue should now be fixed, and a dev build can be downloaded here to test it out. Some servers were sending useless empty tab-list item updates, triggering a crash in Minecraft Console Client which was expecting at least one item to process. Also it wasn't processing multiple items sent as a single tab-list update, this is also fixed by the way.

[k3ldon]

now works fine, thanks

Great! Closing the issue. Feel free to reopen if needed.
