Top mods / Fastload
Not listed
Fastload doesn't list Minecraft 26.3 on Modrinth. The newest release it lists is 1.20.1, on Fabric, Forge, Quilt.
Also lists 5 snapshot or pre-release versions, not counted here.
This is what the mod's author listed on Modrinth, not a test. A listing doesn't prove a mod runs on your setup, and a missing listing doesn't prove it fails. Versions must match exactly, and files published elsewhere, such as CurseForge, aren't counted.
