As I sadly did not get any help and this plugin is clearly not getting updated. Just closed/delete this thread.
TC is a Huge Plugin, and its a ton of work for one Person that may have not the most time of the world.
Build #178 or #179 is working, there is a Working verrsion out there.
There really are not that many bugs in the latest build, @rutgerkok does an amazing job at keeping terrain control working. I am using 1.12 and the terrain control pre build, yes it's got a few annoyances but there are work arounds for them. I really appreciate the time and effort put into the builds. <3
