Gonna file the two glitches I found in two separate threads.
First, the QoL changes and addition of ranked mode have breathed new life into this game for me.  Thanks a ton for implementing both.
Anyway, this glitch is something I call “Phantom Fighter Move”.  Allow me to explain:
Scenario:  I have two separate stacks of German Fighters.  One in Karelia, the other in Germany.  During Combat Move Phase I move both of them to attack Caucasus (2 moves away from Karelia, 3 moves away from Germany).
Battle Occurs, all of my air units survive.
NCM Phase:  I should only be able to move my Fighters that started in Germany one more space, and my Fighters that started in Karelia two more spaces.  If I individually make my moves, this will work as intended.  After I’ve individually moved each of my Fighters with two moves left, I will only be able to move the remaining Fighters one space.
However, if I use the new “SHIFT+CLICK” feature to move the entire Fighter Stack at once, the glitch comes into play.
For whatever reason, SHIFT+CLICK"-ing the Fighter Stack in Ukraine lets me move all of them 2 spaces, even though some of them should not be able to move that far.  This trick allows for illegal Fighter Movement that is earth-shatteringly overpowered in arenas like the Pacific, where fleet positioning is entirely based on the limited air range of opposing FTRs/Bombers.
NOTE:  I do not know if this occurs for Bombers as well as Fighters.  I have not tried it because building additional Bombers is usually poor play and I am only playing Ranked Games at the moment.
If this bug is not reproducible on your end, it may have just been a one-time thing for me.  Sorry for the false alarm if that’s the case.
Not a huge bug, but a bug nonetheless.
Thanks for listening.
