Well, first day of minecraft and i think iv'e done a pretty damn good job! Opening up a shop tomorow, but one thing, iv'e been trying to make a lava moat but i can't drop lava, and the lava stays in my bucket forver. The only way to get rid of it is to drop it or put it in my culdran. Is this a server issue, something that we can fix, or is this a gamemode issue?

Are you playing in the FP server? If so lava is probably disabled to prevent griefing.

I think that this is a plugin anti lava, tnt,.... So you can collect lava, and you cant drop it. I had the same problem on other server with lava.
