I'm now May 1940 and even it's still early in the campaign, I noticed:
1) no Spy in-/ex-filtration mission yet : I can't remember when and how you get these offered and I don't like to miss them
2) convoys : Not seen one, second patrol north of IRE completed, not sure when exactly they were established by the allies, however I already get BDU messages, but all of them far off my position though)
sorry if this was asked before but this is a huge thread
thanks
