A comprehensive server-side bug fix plugin that prevents crashes, player kicks, memory bloat, and combat desync issues in Hytale Early Access servers.
Running a Hytale server means dealing with Early Access bugs. HyFixes patches critical crashes, player kicks, and memory issues that plague servers during this development phase.
What Does This Mod Do?
This server-side plugin consists of two components that work together to fix known bugs in Hytale’s core systems. The runtime plugin handles most crash prevention, while the optional early plugin fixes deeper networking issues.
