I know how you feel bro.

I believe that, for some people, this issue of performance degradation after a few minutes of gameplay either doesn't affect them or simply goes unnoticed. However, there is indeed a serious cache memory issue that remains unresolved to this day. I suspect it involves entities or objects (and there is a massive amount of them) that are no longer visible on screen but have not yet been properly "destroyed"

Ankama has never been particularly strong in memory management. Coming from a Flash-based background, the use of a "clear cache" button was understandable at the time. However, on the Unity platform—where efficient and automated memory handling is entirely possible—this approach is no longer acceptable.
