Maptext is acting strange. I was trying to experiment and figure out the new maptext with the lack of documentation, and was coming up with nothing. I hopped onto Epic to see if Yut Put was there, since Epic uses it. I was going to ask him about it. He wasn't there, but I soon realized that the maptext wasn't working on Epic. I do not know of other games that use it yet, but I will test others if they are pointed out to me.

Here is a screenshot. When I approach that sign, maptext should appear so I can read it. I received no text.
