On a populated server, and my player model will inconsistently stop rendering while near other players. There is no error message above my model, and the error log is empty.
The model loads perfectly fine while I am on my own, only sometimes while other players are rendered.
It is also fully rendered in first-person (thanks to first-person model mod), but inconsistently disappears for others and myself in third person.
The model is a experimental export.

Said server has a rather bulky modlist, but here it is anyways:
