Not an Issue Calling kill - but already IsDestroyed!? build/block.halfheight (BuildingBlock)

i have a screenshoot of this error

http://screenshooter.net/101978843/mlheubc

it stops after a sec..

 

It's only a warning and isn't that bad, you probably have two plugins doing similar things, which is removing the block (build/block.halfheight) at the same time so one of the plugins is going to remove it and the other one will be too late to do so as it will be removed already by the other plugin and will show that warning.

 

to complicated that what you wrote 4 me xD but if its not a serious thing then fck it
