IL-2 46' 4.12 bomb bay doors close in replay(BUG)

[FlyingRustBucket]

I created a scene in full mission creator for movie making purposes.
I saved, I started the mission through the editors play function and started recording a parafrag bomb attack run on two columns of vehicles with the B-25.
When I started the replay, a few seconds before the bombs drop, the bomb doors close. The bombs still drop and blow up, but they are invisible.
After the bomb run the doors open and close again(probably the moment I closed them).

I have just installed .1 and .2 for 4.12, but they didn't fix it.

I might try another recording, see if the problem persist, later.

EDIT: Tried re recording. Problem persists. Bombs donnot actually fall at all. there are no impact effects or explosions. The vehicles just explode. Also, the doors close when I stard dropping bombs.

EDIT2: Tried Il-4. It has no bomb bay door bug. I forgot to mention that I have no mods installed.
