When generating new chunks on smp this crash happens. Looks to be when it tries generating a village. Restarting the server fixes it and no village generates http://pastebin.com/wMhZaHPe

I'm seeing the same crash on Forge 1448. My guess is that the Tropicraft recommended version of Forge being 1291 is because it has not been updated for the Forge fluid changes. I can provide logs if needed.

Interested to see if this is an issue in 1.10.2. If it is, feel free to re-open or create a new issue.

Haven't used 1.10.2 too much but will give it a go sometime soon maybe
