After playing Grounded 2 for a while I disabled crossplay since I am not interested to play with other players on another platform than Steam. I mainly play with my family members who are also on steam. Thus in my mind I didn't need crossplay.
After playing solo for a while my son wanted to multiplayer again. I couldnt get this to work until I enabled crossplay again. To prevent confusinon I would recommend to rename Disable Crossplay to Disable Multiplayer because this is effecively what this option does.
But this wasn't the biggest problem, after I reverted back to Crossplay Enabled I lost all resources I collected while Crossplay was Disabled. Fortunately after Disabling Crossplay again I was able to transfer all resources in my backpack to a chest. Then I enabled Crossplay again and the character reverted again, but since I had saved my backpack items in a chest, I was able to pick the up again.
Kind regards,
Kalin
