Ice and Fire is a mod that adds dragons, sea serpents, and other mythical creatures to Minecraft. This is a patched version of Ice and Fire 2.1.13 for Minecraft 1.19.2 (Forge).
What was fixed:
- Resolved a critical performance issue where frozen or bugged dragon entities generated 600,000+ UUID collision warnings per session
- The root cause was duplicate UUID assignment in EntityDragonPart — multiple dragon body part entities were being assigned the same UUID, causing the server to repeatedly log collision errors
- This log spam caused severe server performance degradation and inflated log files to unmanageable sizes
- Internal classes FrozenProperties and SirenProperties were renamed to FrozenData and SirenData to resolve the underlying UUID conflict
Left unchecked, this bug would progressively degrade server performance the longer the world ran, particularly in areas where dragons had previously been frozen or killed in an unclean state.
This build was compiled for use in the Akashic Records of Tensura modpack. No gameplay changes were made — only the UUID collision issue was resolved.
