Fastvancements
I noticed that a lot of the existing advancement optimization mods are either outdated, carry unnecessary libraries, or cause compatibility issues when you have a big modpack.
I built this to fix those problems. It takes the best features from the other optimization mods and adds a few more on top, all while staying lightweight and stable.

Currently no mod comparison benchmarks are available. I could rush and do one but it would be inconsistent. If anyone is willing to help with it, contact me!
