I have come across a problem using the moving want from 'Not Enough Wands' ver 1.12-1.8.1 and Buildcraft ver 7.99.19. Normally when you break the quarry block with a pickaxe it breaks the quarry frame and then you place it down again and it creates a new frame. When using the moving wand it picks up the block and places it fine creating a new quarry frame but sometimes the quarry frame remains then if you place the quarry block with the wand it should be removed from the wand however it is now 'stuck' in the wand and you can now place as many quarry blocks as you like but they don't make the quarry frame so are not usable. I was able to reproduce the problem in singleplayer as well. Also one time I placed a random quarry block it just started spitting out random blocks like it was actually mining, I ignored this and eventually it did crash the server I was using which wasn't mine :(
Here is a link to the crash log i got from one of the mods of the server https://pastebin.com/wWqqyVtM

Moving Wands issue: romelo333/notenoughwands#104

this sounds like a not enough wands bug rather then buildcraft as we have no specific integration with this mod or control over how that mod behaves when placing blocks

Ok I've reported the problem to them as well.

I'll track the buildcraft-crashing part of this issue here: #4472, and that should hopefully be fixed in-dev (although there isn't a relevant test build out yet).
