Can't reload tank on cap point anymore

I got ammo racked on the VT5 and drove to our team cap point to rearm, but no rounds are loaded.

I get the reload icons going and the “ammo counter” goes up, but no rounds actually get loaded on the tank.

My autoloader keeps being empty, and the rounds that are loaded don’t appear inside the tank despite the ammo counter going up. The crew also doesn’t reload anything into the autoloader despite the ammo counter showing plenty of ammo available.

Already happened twice today, exact same circumstances.

On the replay it shows rounds appearing outside the ready rack but the crew doesn’t load them
