Buildcraft is screwing up on my hosted tekkit server please help

[godspire]

Imnot sure why, but when someone uses buildcraft machines on my tekkit server, it basically corrupts the world and I don't know how to fix it ive had to reset the map at least 3 times.

I really have no idea what to do I think it may be because its in a protected region from world guard.

one thing that it says on the server is

16.02 05:27:45 [Owner]~godspire ran command Message of the Day
