merge

I'm having a bit of trouble. I'm trying to replace the pet house on DaisyNiko's Rolling Hills farm map, but the pet house appears unchanged despite editing the tilesheets. Is there something I'm missing?

Hey, my autistic self has fixated on merging png to tilesets and such lately. I did all my game already and there is nothing new out off Naver that I want to merge or anything, so would like to get my fix by offering help to anyone here that needs help merging anything. Just post here or drop me...
