Past tips

Since version 1.2.8, we introduced the Critters and Companions mod, which adds more vanilla-style mobs using GeckoLib as the rendering library. Our tests didn't show degrading server-side performance so the mod stays in the pack for now.
In version 1.2.8 , we introduced HUD+ this adds several icons that can clutter your view. You can customize this by pressing the 'O' Key.
