Model Precaching Problem.
Because the map creates a endless atmosphere for you,
then in map someplaces will be no end but no model is precached(some of them will choose to use invisible wall.)
so, if you see a non-precached model, your game crashes and now there is no method to fix
to BTgame::
i tried my version(7.1) is only lower the model which is not existed.
to who downloaded my version in my post, still have this problem.
