I'm having an issue with buildcraft 7.1.15, when I use the quarry In the normal and creative modes it builds the frame and drill, and digs away as it should, but the blocks are not being put out...I tried pipes from different sides, tried more power to the point it was clearing layers in moments, and even tried putting a chest on the top with no piping and no luck. It does pick items up that I've dropped in and puts them through just fine. I've tried different versions from 7.1.14/.15/.16 and 7.0.4 even, hoping an older version would work. All attempts were made on a different save each, and each was done in both creative and normal (separate saves). Not sure how to fix it myself, but I can provide whatever you need to look at it...it's probably another mod, so I still need to test with only BC installed.

I Can Post any files Desired but I do have this Video I made today before posting this:

EDIT:

Well...I found it...and it's a mod I like almost as much as BC...I added "AutoPickup-1.7.10-1.1" after Forge, BC and BC-Compat. The blocks weren't being taken but deleted like before, so I removed it, and added the other 108 mods I had before and ran the game in both survival and creative...and whilst I love the mod, I'm going to have to remove AutoPickup, as Buildcraft is the best !
