Hi,
I was recently editing a tilemap in a game of mine to compare color schemes of a layout. I changed the color of some tiles and then after I saw them in the layout, I hit the undo button to return them to their original color. The screen suddenly got a red tint and it told me there was an error with changing the duration of a non-animate object which makes no sense because you can't even do that in a tilemap. Here is a picture of what it looks like.
Does anyone know what's going on?
