Ok, I'm starting to wonder about that periscope....
I started my next patrol and sailed out of kiel, making sure to check the periscopes, both were clear as crystal. Sail 200km from nearest land, save, exit, run SC3 Gen to get mission orders and what not, come back, and now the attack periscope looks like this:
Is it because I didn't launch SH3 from SC3 commander when I reloaded it after using SC3 Gen? Its rather irritating, I've
never had a malfunction before using SH3 Commander, and now I get two identical ones in a row, yet the periscope was fine leaving port?!? Would reloading my save using SC3 Commander to launch the game fix this? I never go back on saves (in fact I never save/quit in the middle of the patrol except to use SC3 Gen) but I'd be willing to do so to fix this unfortunate error.
[edit]
Ok, even more bizzare, I reloaded my SC3Gen save, checked the periscope, just fine! On a hunch I dive (first dive of the patrol) and pop the periscope up, now its
Blurry! Gah, what the heck?!
