So MajorWang and I renovated the slime farm. We spaced out the platforms so that there is a 3.5 space gap which allows large slimes to spawn. With that, I also added a cactus killer instead of a water drowning system so they die faster. There is still an issue with slimes despawning.
From what I can gather about the speed it’s at about a stack an hour now, although it should be much higher. I’m not sure if this is due to the slimes swimming against the current then despawning or what, but I intend to figure it out
