To discuss gameplay and design questions about this scenario
(Sorry can't figure out, how to post screenshots)
"Stay away. This is US territory." Probably just a graphical glitch, as the seazone is treated like a land region.
Here I wanted to move my loaded sea transporters, but didn't get access, because they were covered by the Marine unit.
Save files are available if needed.
Indeed, the flag looks like a bug, it happens during some particular naval combats, we'll check it out. For sure a glitch
Yes, the second issue is also known when the map region is too small (the land unit is partly 'hiding' the naval units during the naval phase). But, normally, during the Naval Phase, if your marines are 'on board', they should not pop up as only naval units pop... will check that ergonomy issue too
