FPS loss after firing RB-15's

This is a issue that have started occurring to me since the last two updates. I can't say how universal it is even for me as I have only had it happen in the same online mission over Normandy that I have created and are hosting for myself and friends.

As I said, it's a mission over Normandy, some air to air action to begin with (that I usually fly in the Hornet) and once that is taken care of I go ship hunting in the Viggen. And every time I fly the Viggen and fire my RB-15's my framerate starts to drop, by the time my missiles hit my framrate is below 1, and that usually leads me to crash (or I simply eject), and as soon as the Viggen is gone, my framerate is back to normal. I can then take another plane and everything seems to be working fine again. That is until I fire RB-15's again, then the same thing happens.

I've used the same basic mission to host for quite some time with only minor changes, and

Unfortunately I haven't fired RB-15's in any other mission, so I can't say if it's mission dependent or not, I will try to run a different mission tonight where I can fire RB-15 and see if it happens in that as well.

Ok, updated to very latest version (released today), edited the mission very slightly (removed a Tu-95) and tried hosting it again (with me as only player). As soon as I fired my RB-15's framerate started dropping and before the missiles had reached the target I was below 1 fps, couldn't even manage to leave the plane by then, so I resorted to killing DCS.

Made a new mission, similar but on the Caucasus map, no problems what so ever on that one.

I have added the problematic mission here, needs Normandy (of course), Viggen and WW2 Assets pack, in case someone wants to try it to check if they get the same result.
