Pianus Spawn Rate

This happens to every monster spawn that's handled client-side (as in the spawn time is listed in the data) as a opposed to server-side (blue notice usually, mostly area bosses). Every time any person enters the map or does something in the map, the time it takes each monster to spawn increases. Left pianus's spawnrate is indeed 36 hours in the data.

Offtopic: I heard you were killing all the piani in windia D:

Could you elaborate? I never cared to dig into the architecture of how ms really ticks because I figured it'd be impossible to get the info from someone.
But how exactly does you entering the map and/or doing anything in it change the time it takes to spawn?
