Map drops seems very odd

I have been running T16's with 4 stones for a while now and noticed something odd.

I have Beach favorited 8 times and Ashen Wood 1 time.

I have noticed that when I run Beach, it is rare for me to drop the Beach map. Almost as if the favorited Beach does not count. I barely drop any of those. I do drop many Ashen Wood though. The opposite is also true when I run Ashen Wood. I cannot drop it, or mostly will not drop any of those, but I will drop tons of Beach maps.

Seems like there is a bug with map drops within the same map with favorited maps.

Am I the only one that has noticed that?

Running 4-Watchstones for 3 days and i can't sustain my t16's without Alva temples,azurite mines and others additional map drops location mechanics.

Im Favoured Defiled Cathedral, and there only like 4-5 of them in the stock withiut actually running them.

Not only maps feels weird. Drop in general.

In + it is less garbage.
In - it is... weird and too scarse.
