I'm banned from my server.

Well... this is probably the most embarrassing time I've ever had on Bukkit, but I am banned on my LAN server. It all happened after I made a plugin where when you click a chair it will spawn an arrow, and set the player the passenger of the arrow which looked like the player was sitting in a chair. I also made a method for when you shift you eject. Obviously something terrible happened... As soon as I tried to get out of the chair, I was kicked from the server (my LAN server) with the reason "Nope!". I've never seen this before either. I tried to pardon myself in console and all that. I wasn't sure if I should put this in the development section, because i'm assuming this "Nope!" screen is apart of Bukkit, not my plugin. I've tried to restart/reload server too. I'm out of ideas, if anybody could help that will be great! Thanks...


[Update]:
In console it says "Ace_LOS was caught trying to crash the server with an invalid position"

 

@AcePilot10
It could be an anti-cheat plugin, judging from the log saying you were ¨caught¨. If you have one, I'd suggest that you disable it and try using your plugin, though still do what @timtower suggested.

 

@AcePilot10 CraftBukkit does indeed do this when something goes horribly wrong. It doesn't ban you though, and teleports you to the spawn as well, so this shouldn't be repeated unless you try to do it again. As for the problem, try following @timtower's suggestion. If you're still getting it... *shrugs* provide server logs maybe?

@LordDarthBob Nah, it's a message found in CraftBukkit, and while a plugin could copy the message, I don't find it likely. Since it's in CraftBukkit, though, I doubt it's a plugin

 

@LordDarthBob I use this server only for testing my plugins, no anti cheat. @timtower I have removed all my plugins and still nothing. here's what the console throws when I try to join.

Code:

@AdamQpzm
Wow. I didn't know that Craftbukkit came with much native anti-cheat stuff. Nice!

 

@AcePilot10 Yep. As you can see, your Y co-ordinate is "NaN". Naturally that just won't do. Follow tim's advice: Delete your player data.

@LordDarthBob Most of the stuff it does have is centred around server stability - like this one, for example, is to prevent clients from sending packets that contain co-ordinates that aren't a number. Such things can't really be handled by the server, so rather than crashing, it simply kicks the player

 

@AdamQpzm
Makes sense

 

@AcePilot10, clear the player data folder of the world. That should do it. I don't think I've ever seen this before though.

 

@timtower and everyone else, thanks so much for the help.
deleting my player data fixed it.

 

I am glad to hear this I had no clue bukkit included some anti-cheat mechanisms, that's pretty cool.
May as well ask the mods to log the topic (since it is solved).

 

@Markyroson I guess the error happens when your Y glitches, because as @AdamQpzm replied, in console it says my Y is NaN. The only plugins I had was a plugin where an invisible arrow would spawn at the location of a stair. Then when you mount the player on the arrow, it looks like the player is sitting. So it must be something inside the player being mounted on an arrow
