Notice the AP for the Soviets on the second picture, it is 625. Did you intend to remove the 500 cap.
Note, this is a test game where I am playing around with command structure so I gave myself double the AP points. Until 103 Beta, it always capped correctly at 500
Here is the save prior to the 96th vanishing. I ran the turn three times and it disappeared each time. Watching the AI turn, it did not attempt to supply it via airdrop, though it did others around its location, nor is there ever a battle. Its there, then during the AI 3 9 cycle its gone.
Not serious by any means, as this is just a test run for the first year before I start a "real" campaign.
I have created rather an outlier situation given my setup. I think what is triggering the issue to 625 AP is that this is the turn the Volkhov Front becomes active. When a new front enters, 125 AP are added. Now, I think this might be 500 AP to max, note the addition from 473 (previous turn, plus 50 AP for the turn plus another 50 for my 200 AP setting) are not carried over and go to 500, then 125 are added because of the new front coming into play. This could be the intention of the devs where the hard cap of 500 is violated, or not. Certainly a weird situation mainly because I am playing around here. I do not think many Soviet players have the AP surplus I am running.
I've sent the save and bug to Gary for the warp move. As for the admin points, as long as the Soviet APs fall to 500 on the next turn, I'm ok with it allowing the extra 125 points over the 500 CAP on the turn the front arrived.
All understanding comes after the fact.
