Version (please complete the following information):

• What version of TerraPlusPlus are you using?
  terraplusplus-1.1.0.619-1.12.2.jar
• What version of the BTE Modpack or Server pack are you running? (If applicable)
  N/A

This issue might not be related to Terraplusplus, but to the Cubic Chunks mod, which probably has some conflicts with one of the mods you added to the mod pack.

For this reason, see the Cubic Chunks compatibility report:
OpenCubicChunks/CubicChunks#448

It's definitely anything that is World Gen related (my guess being Serene Seasons, GUNS RPG, Dynamic Trees, Dooglamoo Cities, The Lost Cities, etc)
Or could be you running Sponge.
