Thanks for taking your video down this morning Sam. This video demonstrates the bug I've been trying to keep under wraps since I got basebuilding working under 1.7.7.1. All basebuilding items were able to take damage, most noticeably from explosions but early on we also discovered even a hatchet would destroy things. We are the only server to my knowledge who have now fixed this bug.
Thankyou to the guys who were already aware of the problem and did not use it for exploits, and thankyou to MM for getting me thinking about it again today when I first saw the video. I had an idea this morning at work and it paid off
