I found the tank... Its just disappeared from my carousel and I cant select it easily.
i have to go to t49 >research>M41>display in garage.
I will reload Aslain mod pack>latest version
I clicked the menu shown in jpg 14 and jpg 15 and my M41 disappeared from garage.
Crew and equipment also gone and i got no credits from it
Its a 5 skill crew with 4000 battles in chaffee and M41
Please help
