Controller inputs stop responding in mountainous areas

Since Update 3, I’ve experienced a strange issue where my aircraft continues to fly normally, but my controller inputs stop responding. This has happened multiple times, with different aircraft (e.g. 737 MAX add-on, A321 mod), so it doesn’t seem to be linked to a specific aircraft.

When the bug occurs, the plane itself does not freeze — instruments and systems keep working, and if I use the free cursor mode, I can still interact with the cockpit. However, any direct inputs from the controller (flaps, gear, etc.) are ignored.

I have only noticed this problem when flying near mountainous terrain, never over flat areas or at cruise. It feels like the simulator is still running, but it simply stops recognizing my controller commands in these regions.
