Demo mods and Early Access compatibility
Quick answer
Check the mod’s supported game build before installing it. A Demo mod does not automatically work with Early Access.

Compatibility varies by mod; no installed-mod test claimed.
Read the compatibility fields
Use the actual mod page to compare app, version, requirements and update date. Back up saves before a change, and keep a record of the files you add so they can be removed cleanly. This guide does not certify any specific package.
Test without mods first
Reproduce a gameplay problem on a clean setup before attributing it to the base game. In co-op, tell the group what is installed and agree on the same setup where required. Steam Workshop and official mod tools were not listed in the checked sources; community tools are a separate route.
