Sometimes when pasting buildings, items tend to break and despawn. This have happend to mostly signs, but also deployed items like large battery, teslacoil and boxes. Seems when placed close to other items. I'm not sure.

It also seems random. Ive pasted the same building many times, and the stuff that breaks/despawns doesn't always do this. Thansk again for a great plugin. :)

I'v downloaded the 4.1.17 once it was released. 

Should i make new copy's, is it the savefile that is "corrupt" from the outdated version?
