Playing it a bit for the first time against other humans, and there's some various minor issues that I'm starting a thread to collect, and for other to feedback upon. Easier to notice things that are hard to notice when you're new to a map.
Issue 1 Russian Winter game notes text should clarify that it also protects russian ships from being attacked. edit: it also prevents rocket attacks.
Issue 2 sz 55 units are really easy to miss when looking at the mediterranean, not sure there's any good solution to. I epically failed and italy got invaded twice because I didn't see transports in range. Transports are visually below the horn of africa, it's where there's the most space, but it does make them quite hard to see; (i.e. you could position to see most of ethiopia and still not be able to see the fleet)
Issue 3 another user noted that the "you can't build capital ships here" giant X'd out shipyards are quite ugly to look at. They're also not always that clear; I still forgot that it prevented building carriers to the south of italy (since it's rather unusual to say one specific location next to a capital isn't allowed but the others are, it's the only place on the map like that). There might also be a way to make it clearer visually that it means no capital ships, but doesn't affect regular ships.
Issue 4 Japanese National Advantage Battle fleets (the bbs provide support one), the game notes should specify it doesn't activate until after the first turn.
Issue 5? Objective wording? iirc last time I checked some of the objective wordings don't quite match up with their actual requirements, so it'd be good to synchronize them Leaving this here to remind myself to look at it.
Specific issues (comparing objective wordings on the objective tab, to notes, and to xml file)
German objectives 2&3, objective tab incorrect; notes and file match.
Issue 6 If Germany acquires Rockets before the national advantage that gives it to them in round 3, they appear to just get nothing. Perhaps they should either simply not have a chance of getting rockets if national advantages are enabled, or if they already have rockets then they receive some other bonus instead?
issue 7 bombard casualties don't return fire is set as the default; this is despite v3 rules usually have bombard casualties returning fire.
Issue 8 Japan's national advantage that improves its battleships when attacking also affects bombards (and can improve the bombard of their other ships), game notes should be modified to make this clear)
issue 9 notes should specify which territories are required for suez canal use and when they're required.
issue 10 game notes for improved factories should specify it only improves locations with production >= 3
issue 11 kamikaze's are placed at end of japan's turn; which means that if the sz has no other allied units in the area, they can be killed by a single enemy plane with no risk. it often feels like a weak national advantage; due to its move 1, it rarely gets to attack anything; and is prone to being wiped out on a defense at a some point. additionally, on defense they fire even though they're rolling a 0. So any attack on a stack containing kamikazes will kill all of them without them inflicting any damage.
issue 12 contrary to game notes, bombers can not use paratroopers. The paradrop plane should perhaps be unavailable to build until you have paratrooper tech; since it has no purpose before then.
