SZ 110 is a weird one, you have British, French and German territories. SZ 96 has Italian and British, as does SZ 76. SZs 20 and 36 are British and Japanese.
We should probably assign sea zones on those instances?
SZ 96 and SZ 76 should be Italian, since they control 2 of the 3 bordering territories. SZ 20 and 36 do not need to be assigned as England and Japan are not at war yet, so no matter what ships are placed there, combat won’t occur if Japan does not declare war on England (or England on Japan).
SZ 110 is a bit harder, perhaps we should state that no one can place units there? England has plenty of other sea zones they can (And probably should use) and I’d like to avoid a situation where France is reinforcing England senselessly (France has 99 IPC, that’s 1 Infantry for Paris + 2 Loaded Carriers, 3 Destroyers that could stack defense for England in SZ 110 if allowed.)
