Haulora MP runs on one game version per game:
- Euro Truck Simulator 2: 1.61.1.9
- American Truck Simulator: 1.62.1.1
When a new game version comes out, Haulora MP moves to it fully and drops the old one.
Steam updated my game too far
When Steam updated the game past the supported version, the launcher tells you. Pick the beta temporary_1_xx it names in Steam: right-click the game > Properties > Game Versions & Betas. SCS keeps the previous version there. Wait until Steam has finished downloading.
Any other beta (such as public_beta) blocks Play. When Haulora MP has moved on to the new version while you are still on the old beta, pick None again.
