Hi, I have a server running FTB Ultimate. I didn't make any changes from the default install and it's been up and running for about 10 days now. I can't say for sure, but I'm almost positive I was able to place water when I first started playing on it. But now for some reason I'm unable to place lava or water. While searching for possible causes I came across this video: which is about fixing the same problem with a plugin called Essentials, but I don't think that's part of FTB. The behavior shown in the video is exactly what happens to me. I place the lava/water and it appears briefly then disappears and my bucket never empties. Any ideas on how I can fix this?
