Fixed Pregen issue where the progress updates wouldnt stop after it completed
Fixed Pregen issue when using writemode PaperAsync, would stall for a long time then eventually finish (will now generate up to the thread count as a buffer like before) paperasync is now slightly faster now too
Fixed Pregen issue when using Spigot (very slow) in which all chunks in the region were requested at once (basically unless you've configured your server not to shut down after freezing, it would)
Fixed village paths & other decorations placing on top of objects & trees
Multiverse Core support is now working as expected. To create iris worlds please use /iris create <world>. If you have multiverse installed iris will set up the world properly for you.
Some pretty decent performance improvements. With just paper flying around you may see higher chunks per second in studio mode.
