I was there two or three days ago. There was a problem with the waves not starting when they should. Either nothing or like a tiny little ripple.
But then they did start working and worked normally, for the most part (some delays, not many.)
I went and got a salad and was lying in the sun for a bit. When I went back in, the "bunches of smaller waves" thing was fine. I forget the actual name of that, but it worked.
People who aren't very familiar with Typhoon Lagoon would likely not have known there was any problem at all.
Everything else was typical Typhoon Lagoon. Well, I rarely go on water slides and didn't that day...but the lazy river was its usual self and there is nothing new about the wave pool having a textured surface on its floor.
