Deployer won't work?

[ComplicatedThings]

The deployer from RedPower2 isn't working to well for me. When I place it down and shove some blocks in it and give it a redstone current, it places it down. When I place a bucket in it, with water infront of it, it does nothing. It wasn't always like this, before I updated the Tekkit launcher thing when it told me to for computer craft fixes I believe, it stopped working. Before that it would just collect buckets of water, now it doesnt. Please reply if you know what is wrong.

Do you have any mods that prevent players with interacting with the environment, such as Zmods protection/interact zone protection?

If so, that's the reason. For some reason the protection also applies to the machines in the zone preventing it from interacting with the environment.

Nope, I have done nothing to the sever. It used to work, and now it just stopped.
