In one of my PBEM game using GG1942 1.04 mod, when 4 Destroyers attacking 1 submarin, combat report shows the submarin fired nearly 30-50? times but all with 0 dice(I am lucky?).
This happened only once and when I reloaded it didn't happen again. Hope this won't cause serious problem if the submarin could fire next time.
This has been around a while. I've never figured out a consistent way to reproduce it (from prior to the combat start) and have not been able to debug it.
From what I have observed, it appears to be a display issue (the save combat report is corrupted) which does not impact the outcome.
