Server will not generate modded dimensions

[Anyone700]

I'm running the latest forge server for 1.7.10, build 10.13.4.1614. I have several mods that add new dimensions. Runic dungens, nomadic tents, mystcraft, dimensional doors, extra utilities, and I believe thaumcraft also adds a dimension. But the server seems to be only able to generate vanilla dimensions, with users who leave getting a ticking screen, out of range, or dimension not generated error. Looking at the server world, the dimension appears to be generated, however,  judging that every nomadic tent tries to send you to dimension 68, the dimensions do not appear to be registered
