Tank lost because of low fuel [issue solved]

[Delta66]

After finishing the GC 44 west Eindhoven scenario, when I start the first GC 45 west scenario, one of my Panther tank has disappeared from my core, (or come back with a strength of zero if If I select reform unit).
After studying the previous scenario, I noticed that my tank finished with low fuel (5/63 fuel). Using the cheat code to add some more fuel, make my tank appear properly in the next scenario.
I know this happens for aircraft if they finish a scenario with low fuel, but I had never faced this situation for a ground unit, is it how the game is supposed to work? or is it a bug?
Actually I have played all the campaign without any cheat and I'd rather finish it that way, and don't use cheat so close to the end.

I've never had a smiliar issue and haveing the strength reduced to zero usually means it got destroyed. So it's either a weird bug or just something else. Have you looked at the replay, that might shine some light upon it.

After more investigations I found where the issue come from. Actually I loaded the wrong core when staring the new yearly campaign.
Sorry, my bad
