Describe the bug
Originally reported over xJon/Tekkit-2#276:

When using a mining turtle to excavate I went down to it a few times with a bucket of water and instead of functioning normally the turtle made water source blocks where the bucket flowed and ended up making a big pool of water in all of the holes it mined. From what the staff on the server APOC said "The turtle is recognizing the water as a block and tries to mine it but for some reason it's placing it?" I've replicated this issue in survival mode so its not just an issue on that server, and it's just become a big nuisance at this point. I understand this might be kind of a niche problem because not everyone would have their turtles interacting with water like that, but would appreciate if it could get fixed. (P.S: This seems to occur with more than just the mining turtle so it potentially happens with all of the turtles)
Thanks.
