I'm no good at reading error reports from the console, but when I tried to use this mod/plugin on my 1.6.4 MCPC+ server, I got the following crash report: http://pastebin.com/qVx3HWgi

I then thought "Maybe something different might happen if I put it into the 'mods' folder instead of 'plugins'", so I did, with the same result. Here's the crash report from that attempt if that's important: http://pastebin.com/S88cA30f

Anyways, not going to fix this, since it is a 1.6.4 issue. See issue #246 for 1.7.2 MCPC+ compatibility.

2.5.0 has some problems on MCPC+. Build 57 should work.

I tried that build. It seemed to work at first, but then I got another crash report to show you: http://pastebin.com/D9SSk7eD

*This is from a singleplayer attempt. It didn't seem to work on the server either, though, which is why I tried to do it in SSP with the intention of importing it over to the server. On the server, I got this error: http://pastebin.com/9iuRU5cN

Seems like a mod conflict. The first stacktrace mentions that the structure ketlark.mod.beer.ComponentVillageTavernier isn't registered. The second stacktrace mentions that tconstruct.worldgen.SlimeIslandGen.generate is using an invalid number.
