[2021] Why dont my mines reload/stock in the naval War Thunder games any more?

From Red Skies changelog:

Naval fleet model, damage model, characteristic and weaponry changes:
Naval weaponry:

Sea mines — lifetime has been increased to 15 minutes. Mine ammo stowages have become unreplenishable for all vessels armed with mines. I.e. the ability to drop mines once in a battle.

It's not "few minutes", but 15 minutes.

It's to prevent spam mines all over the map.

Did not heard on any planned changes for this.
