So I started playing again since the current update and whenever I use any type of seed (doesn't matter what kind) it goes gray. This happens on all my already created worlds save for one (that I've found so far). It was a pre-hardmode world if it helps. I've created a new world, all seeds come out gray. Reinstalled, made new world and the same thing happens. If the hallowed seeds spreads to stone, it comes out looking like normal pearlstone. The grass that I plant spreads into more gray grass, but anything that existed before I started recently for grass that spreads looks normal. I've played around with other things like the clentaminator and that comes out looking perfectly fine as well.
