I figured out that we dont have a Feature or a "Self refresh" of the Maps, which leads to alot of issues sometimes for example:
The SpaceCrack has a bunch of "Dead Cells" which you cant reach and if Monsters spawn in there the Total ammount of the Mobs will slowly decrease.
Same issue leads to overgrouded Dungeons like pron Culverts where if someone stays in the map the eggs keep spawning Monsters while the egg will counted as "Dead" and respawn itself so it generates tons of Mobs.
I know that there is a Function which kinda "Shutdowns" the map if noone has been there for "X" Minutes ( idk maybe 5 or 7 Minutes, should be enough so it wont refresh while killing a mvp).
Another point you guys could take a look into is the Taxes for a shop If selling items for Zeny you have to pay X% Taxes which doesnt exist if you sell the stuff for Coins. Would be nice if you dont have a downside of selling it via Zeny.
