So... No Biomes O' Plenty biomes seem to be spawning. It's all vanilla. However, I know it's important because there's a bulletin board quest for collecting a bunch of saplings..

When creating my world, I didn't have the option to change world generation from the default (which was Biomes O' Plenty), so I don't know what's going on? I've been travelling a lot and still can't find anything.

Additionally, Nature's Compass keeps leading me to the middle of the ocean, instead of the biome I asked for. I think when I was trying to find a flower forest, it did this too, and I just reset it and it found another. But that was the last time it worked, which may have been before an update, not sure. It does not seem to be working in my world currently.

Edit: I also would like to add that I have a TON of chunk loading errors. Like the weird flat drop off terrain when you hit a new chunk type of errors. I have oceans full of land masses that just abruptly cut off at the edge of chunks.

I also could only find one Skyslime island so far and this is upsetting because I can't find a Skyslime island option with Nature's Compass, even though it has options for Enderslime and Earthslime. On top of that, they aren't even islands. They're just little patches you rarely find in the world, with only one tree each. And the slime pools around them are all rendered just like normal water, which bothers me, because I didn't know at first that it was slime. Had I known, it would have helped.
