Bukkit

I install the plugin, and after restart, after like 15 seconds:

The server ran errorlessly, that ensured, before the plugin.
Any ideas?

"Probable Plugin causes: 'WorldEdit and HawkEye''"

It says the main loop is stuck at processing something that is using WorldEdit (could be another plugin using it in a nasty way). Also HawkEye could be it.

Are you running a protocol hack ? You should be sure that WorldEdit and WorldGuard are updated for your server version. Same goes for HawKeye or in fact all plugins that might need updating.

@asofold: Go

Yeah, the thing is, my server is stable, I take great care of that, and just after loading your plugin this happens. I can guarantee the problem is not entirely on WE or HE. Probably something inbetween them and your plugin....this is my guess, I cant know for sure, I am not a dev... I guess we are stuck if you dont know the answer either.

Well the error trace has to do with org.bukkit.craftbukkit.v1_6_R3.block.CraftBlock.setTypeIdAndData !

FriendlyHopper has nothing to do with those, except for preventing some placing of hoppers.

Your HawkEye plugin does hook into internals, that's where you should ask first i assume, also WE.
