MMD Problem: Center bones moves wrong model or even both models


Momo's Minion
So, since a few days I have the problem that my model's center bone will only move the wrong/first loaded model or even both together. It's as if the second loaded model doesn't even exist. Does anyone know how to fix this? I'd really like to pose both models without one running away from the other XD Ah, the camera is acting odd as well btw. When I click on a bone it shifts to the bone or sometimes away from the whole model, even if I click register.
And sorry for asking here, I don't know where else I can ask.
