Confirmation

• I have read the FAQ.
• I have tested the latest development build of Holographic Displays and the bug is still present.
• I have updated Spigot to the latest release for my particular Minecraft version.
• I made sure the bug hasn't already been reported on the issue tracker.

Description

When a player attempts to join the server, the console displays this error message, and then instantly kicks the player. I have no idea if the holographicdisplays error is related to the internal exception error, but i assume it somehow is. I also disabled holographicdispalys and you still cannot join. I tried replacing the scoreboard.dat file (i thought it may have something to do with it, as it says "scoreboardteam"), and it was still happening.

How to reproduce

I have absolutely no idea. I didn't even restart the server. Someone was online, playing just fine, and then left. A couple minutes later i tried joining, and then got this error. Every attempt for someone to join afterwards have caused this same error. I did not run any commands, change any plugin files or do absolutely anything in between the player leaving and me joining. This just randomly started happening.

I see that something using the scoreboard is causing a disconnection, the error shown by Holographic Displays might be just because the player is instantly disconnected. Holographic Displays doesn't use the scoreboard at all. Try removing other plugins one by one.
