Items not showing in co-op

when me and my friend play co-op and i host the game and build things or lay things down my friend cant see them or interact with them any fixes?

Hi duncan,

can you check that both players are on the latest game version and let me know please?

I was playing co-op with a buddy about 6 hours ago. I placed a standard fire down and he said he couldn’t see it. He did re-log and everything was OK moving forward. Both were on current version AppID: 313120 Build ID: 9285485
