They probably hit the shore, because i proceed exactly like you to avoid the scraping sounds when launched.
I didn’t know life boats had damage zone like ships!
Furthermore the sea wasn’t calm, so a wave crashed them on rocks...maybe
Yes for the airfield icons (Japanese, American, British). They looks huge in my opinion. I’d prefer the first ones (in V0.80)
AA gun elevation trouble with Sargo and Tambor (Purpoise also if i remember) with stock conning tower (never upgraded) and stock AA gun (never upgraded also).
From start 41 to mid 42 (never saw any upgrade avalaible anyway for conning tower nor AA gun)
It is the 50 Cal machine gun wich have the problem.
I tried a new career later on (44) with a Gar class, and no elevation issue with the other AA gun (the one with the round aiming circle)
Hope that helps
