Hey Maruno :)
This is my pokecommunity accnt (dont use pokecommunity too much), and I'm actually thesuzerain of reddit (Pokemon Zeta and Omicron). 10k subscribers, not a small fangame.
One of the major bugs I've left to quench that I've found in the system is the black-background bug, where after a battle or a map transfer the tiles, except for autotiles or events all go black, presumable due to a failed tileset load or something similar.
Continuing the game in this state will eventually lead it to crash, most often when you enter a new battle or enter a new area.
I'm assuming this is an essentials specific problem (not all of RMXP) as I cannot find it anywhere I've searched except for Pokemon Melanite, another fangame made with essentials.
So my question is if there is a solution that you know of, if you've heard of this bug before?
Or, alternatively, where is the code that loads the tileset after the battle or map transfer? I thinking just having it refresh every now and then should help. I can't find it for the life of me.
Thanks!
