Tank Reload

I initially suspected something was off, but last night on the MedEVac map I confirmed what appears to be a consistent bug. While operating a tank from the "E" zone and moving to defend "C," I noticed that after approximately two minutes of engagement, the main gun's reload time began to increase significantly. By the time I charged forward to engage another tank, the reload time had stretched to around 7–10 seconds, which made combat extremely difficult.
I've also encountered a similar issue with the APC on the Cairo map. The main gun sometimes reloads much more slowly than expected, and in certain cases, it fails to reload entirely. The only workaround I've found is to switch to the machine gun (slot 2), then back to the main gun (slot 1), and manually press "R" to initiate the reload. This temporarily resolves the issue, but it's clearly not functioning as intended.
