I've been looking for tutorials for building my overworld, and I've been tinkering for a while. I've built something finally, and decided to do the cool thing of triggering events to change the overworld.
The sad part comes when I activate the events, and part of my Overworld turns to black, due to it being a different palette from the rest of it.
If you get in and out of a level, everything goes back to normal (not the optimal solution though)
Some pictures to illustrate the problem:
What is going on and how can I fix it?
