Title:
Server Crashes When Friend Attempts to Join
Launcher Version:
Curse 7.1.6018.41463
Modpack:
FTB Unstable 1.10
Modpack Version:
4.1.1
Log Link:
Details of the issue:
Pretty much what the title says, whenever my friend attempts to join the server, I see "[username] has left the game" for a brief second ([username] being my friend's username of course), then i'm kicked and get the "Server has closed" message. The server window is then completely closed.

Make sure your friend uses the correct version, if that is the case then please upload the crash report
this crash report has been saved to: C:\Users\Nick\Documents\Unstable Server\.\crash-reports\crash-2016-07-06_19.48.54-server.txt
The reason why I say that you should check that is because: at line 16 he joins, at line 17 the server kicks him because of mod rejections and at line 21 it complains about the onPlayerLoggedOut function.

I'm still curious why this forced kick causes a crash which might be revealed in the crash-report so even if this prevents the crash then please still upload the crash-report.

Sorry I didn't upload this one in the first place, probably would've been more useful :p

UPDATE: I found the solution, turns out it was as simple as the server was running on an older version.

But now, there's a different problem preventing him from connecting, I get this:
[15:12:48] [Server thread/INFO]: thegreengast joined the game
[15:12:48] [Server thread/INFO] [EnderCore]: Sending server configs to client for com.enderio.core.common.config.ConfigHandler
[15:12:48] [Server thread/INFO] [Waila]: Player EntityPlayerMP['thegreengast'/81321, l='Masonic', x=-212.50, y=64.00, z=250.50] connected. Sending ping
[15:12:48] [Server thread/INFO] [STDOUT]: [mcjty.lib.preferences.PreferencesProp
erties:syncToClient:31]: syncToClient: style = STYLE_FLAT_GRADIENT
[15:13:19] [Server thread/INFO]: thegreengast lost connection: TextComponent{text='Disconnected', siblings=[], style=Style{hasParent=false, color=null, bold=null, italic=null, underlined=null, obfuscated=null, clickEvent=null, hoverEvent=null, insertion=null}}
Any help with this one?
