I resolved that problem. was because febryary 42 is too early for radars.

i tested it in mid 42 and go fine. thank you friend! you resolved a dilemma for me. was years that i couldnt finish a campaign

Real last question sorry: if for manually refit, i wait that cpu refit my boat in mid 42, it go anycase? (i mean. for avoid being refitted 2 times. an example: if i refit my boat in may-june 42, cut of conning tower, and after 1 month cpu refit automatically it, maybe i should refit again manually it for avoid some bug if happen. so can i refit manually and succesfully my boat, after normal game refit? for avoid 2 refits?).
