I am currently having an issue with Advance Map (1.95 which maybe the problem) in which when I create a cave entering point you can enter the cave but you cannot go out the other way. The warps are in the correct positions, they are also correctly linked to each other yet it is still a one way. I have looked at other caves in the game and I appear to have the same set up as they do. What is wrong?
You need a specific tile in front of the doorway. Copy the exact time from the existing map, or look through the tile behaviour (puzzle piece button) find a tile that looks plain but mentions an exit arrow - or something similar. If you've already got that tile sorry :x
