Keepers of the Stones II: Tough As Nails Compat
Keepers of the Stones II: Tough As Nails Compat is a server-side bridge that lets the Keepers of the Stones II and Tough As Nails mods run together without conflicts.
What it does
Running Keepers of the Stones II and Tough As Nails together causes bugs and instability, because the two mods clash. This add-on resolves that clash, so both sets of features can be used in one world. Both required mods must be installed alongside it.
Tough As Nails makes survival harder by adding health, hunger and thirst, and a fatigue system. Keepers of the Stones II contributes power elements, with climatic conditions such as hot biomes, dirty water and the cursed forest. The compat layer keeps those systems working side by side. Environment: server-side only, so the server needs it and players join without installing it. Files are published for Forge and NeoForge, for 1.20.1 and 1.21.1, under All rights reserved and not open source.

How it compares
Tough As Nail Curios Compat is a NeoForge-only add-on for 1.21.1, under the MIT License, and it runs on client and server. Tough As Nails - Vanilla Pack covers Fabric, Forge, NeoForge and Quilt for 1.21 – 1.21.4 under CC0 1.0 Universal, and it is server required with client optional, so it is a different kind of compatibility layer rather than a fix for this specific conflict.
