It's a strange one I have not seen before doing that but good to know you isolated it to Carrier V2 being the last one shown so the problem would appear to be the next unit on the list
EDIT........ just reloaded that campaign and extracted the scenarios and the wrinkle in this theory is there is no V2 unit shown
There is a J0 carrier though and that could look like a V when those messages are shown..
BUT
further investigation does show that in the FIRST scenario there is a V2 carrier and the last unit on the list for scenario 1 is Carrier V3
It would appear it is crashing the game when the last unit from the first sceanrios experience it being reviewed.....
maybe
I will get this set up again after the summer and see if I can sort it out. I do not want to see all that work lost.
