for some reason, I now have text behind my map.
I'm not sure what I did and how to reverse this.
With something like this, it's hard to figure out without looking at the game; I can imagine a few ways to do something like this, but it's hard to imagine how you would do any of them without meaning to.
Can you share a link to the game?
If not, I'd suggest looking at any JS in your code.
Does this happen at the start of the game, or some time later? That will at least give you a hint where to start looking.
