What's new

1. Reduced excessive Alex’s Mobs Capuchin Monkey spawning to improve server performance.

2. Reduced Capuchin troop sizes while keeping them common enough to maintain jungle atmosphere.

3. Fixed an Alex’s Mobs Skelewag spawning issue that could cause duplicate UUID errors with Drowned riders.

4. Includes previous OMO server-side optimization and log-noise fixes.

This update MASSIVELY improved server performance in and around biomes with Capuchin Monkeys, especially Jungles and Mangrove Swamps. Their population numbers were absurdly high and could bog down or even crash the server despite high-end hardware.

After the changes, our Spark profile became extremely healthy. In our testing with a render distance of 32 and simulation distance of 16, Alex’s Mobs dropped from roughly 35% of the server-thread footprint in those areas to around 6%.
