Title: Destroying Blocks causes Internal Server Error

Version: 3.1.2

OS: Win7 and WinXp

Java Version: 7.0.5.0

Description of Problem:

I have following plugins: Towny v 0.81.0.0, Pex v1.19.3, Modifyworld, Worldedit, BOSEconomy, essentials 2.9.3

When a player enters my server and tries to break a block in a Town he gets kicked instantly. 'Player left the game'

When placing blocks he gets 'Outsiders arent allowed to build'

Also he can destroy outside of the town without problems

This problem also occured with v 3.0.4 , i just updated the server to 3.1.2 because of that

Error Messages:

client does get an error message 'Disconnected by Server internal server error'

Error Log:

push

this is bugging me for weeks now, and it starts to crash the server too

I just deleted towny and you can break whereever you want. But developer of towny says he cant do anything. Its a tekkit/bukkit error

just found out that if you break something (sandstone, torches) with a IC bronze wrench you wont get kicked and cant break, like it should be.

solved

# The amount of time it takes for a protected block to regenerate. Use zero for no delay.

regen_delay: 0s

was set to 1s (by me)

The solution, mentioned above by FatPap actually worked for me too.

Thank you very much for posting it !!!!!
