5" Critical Hits-WAD or not?

[seawolf]

I've been doing some research on 5" Shell damage, and I found that every once in a while (4 hits per 1000 in my case), a 5" HE Shell will cause 1800 flooding when it strikes BE, whereas normally dozens of BE hits will cause negligible flooding

Is this an intended behavior or a bug? I can provide .sac files if it's a bug.

Another user found recently that in RTW1 5" waterline hits and 4" BE/DE could possibly lead to an underflow in the flooding procedures resulting in very high flooding values. It's possible that this is a version of that bug that's still present in RTW2
