I used the search function with as many different phrases as I could think of, and I managed to find a post with someone mentioning this problem, but not much else.
The long and short of it is this: I put the Twin 40mm AA on my boat, and when it fires it crashes SH4.
Every 4th or 5th time I try it, it might work.
I have manually controlled the AA, and it would fire without crashing, jump to the tower, control room, the other AA, then back to the Twin 40, and tried to fire it and it crashed SH4...
I'll keep looking with the search function, but if anyone has a link to a fix, that would be great....
