Ahem,
According to Revised and older rules, you lose any and all units that you do not place. TripleA handles this correctly.
According to AA50 and Spring 1942 rules, you do not lose units you don’t place, you get to try to place them next round. TripleA handles this correctly.
According to Global 1942 rules, you must place all units if you can, and ones you can’t get refunded. TripleA handles it according to AA50 rules instead.
Since gamerman was able to come up with an example that doesn’t deserve a swirly, I’ll add it to the list of stuff to do.
Also, FYI, there are 2 types of “bugs” in triplea: real bugs (bugs that are forced on you), and incompleteness bugs (bugs not forced on you)
Examples:
A real bug would be TripleA disallowing a valid move.
An incompleteness bug would be TripleA allowing an invalid move.
While I do aim to fix everything possible, my time and energy is limited.
Real bugs take priority.
Incompleteness bugs are a very low priority because “you know the rules and be playing by the rules”.
Just like in a real face to face game, there is nothing really stopping me from moving my bomber 9 spaces. But you don’t because you want to play by the rules.
So, disclaimer again: know the rules and play by them.
