cant play with cousin in the same oxgyen not included version

[versu]

Hello, i play with my cousin, we usually select a seed, shared and play the same seed, everybody in different pc but the same map. recently i bought the complete bundle pack with all dlc, and now we cant play the same map, the seed its similar but not same anymore. then i purchased the complete bundle pack for him, and the problem still persist. we are in the same region, none of us has beta updates. i try to re install the game and doesnt solve the problem. both games are from steam. my version say u59-737195-scrpan and he´s version is u59-737195-vcrpan. we check to have activated the same dlc, and notthing. we have no more ideas of how to have the same version. can someone know how to solve this or where to contact to try solve this problem?. we have no more ideas.

I think it's because the Spaced Out! DLC

No spaced out

With Spaced out

You have spaced out enabled (Gray title screen, S following the version number), your cousin does not have spaced out enabled (brown title screen, no S after the version number). All that needs be done is for one of you to switch spaced out on or off to match the other to be able to play on the same seed (Clicking the spaced out icon on your menu screen will toggle it (restart required)).
