Nah you don't need, not a problem!
For this I tried to not to use some tilesets of inner places. Now I'm using all the original and there is no problem now about black houses. For what regards the outside, I'm using the original reborn tilesets of NeoReborn (NeoBeryl, NeoObsidia,...) because the new city has changed a lot of textures and using yours the city is still a little creepy and the plants are not very green as they should be XD.
Then I discovered minor problems about
CavesFRLG.png (it just doesn't show rocks in water whithout the dark-blue border, sorry if I don't have a screenshoot, I'm a bit retarded and I didn't think about it when I found the problem! The good fact is that this only happens in a grotto in azurine lake which is very difficult to find);
Marsh.png (here when you reach Azurine Island there are problems with the near rocks which do not appear and just leave the "hereyoucanusesub" dark blue water ahaha)
I resolved all my problems searching on tilesets, all the other folders seems working the right way, Except a very little bug about eggs in a rectangular green area ahahaha.
Have a nice weekend, btw!
