Also got the problem of tube 7 and 8 not reloading correctly. Only it seems to be worse since sometimes the tube doesn't seem to reload at all. I get a message the reload is complete but no weapon is shown in the tube. After that some weapon may appear all of a sudden. Selecting weapons on those tubes and then using them is almost impossible unfortunately.
Also got a TLAM mission and although I struck the target zone with 10/8 missiles it got reported as a failure. The debrief showed variable names instead of the actual information you would expect to see like how many weapons are left, so it seems this is bugged as well.
This is very enjoyable, keep improving this please
