I dont know if this a deliberate and questionable decision by gaijin but if not the ready racks of all the M18s are bugged and not fuctioning as a first priority ammo rack, none of them load it when spawned and it acts as the final rack when it should be the first given its RIGHT there by the loader, same goes with the T86 but its ammo storage issues are worse because the lowest ammo racks are loading first for some reason which makes no sense at all, it should be the ready rack and the higher hull ammo storages that are filled up first not last. Ammo is even modeled being present in the ready rack when you look at it from above with X ray off
I don’t know if its been like this for a long time or if its recent from something that broke with the updates but it should seriously be fixed.
