I believe I am aware of how to reproduce this.
When playing this as the Host (peer to peer server) items I place down could not be seen by my friend (client) until he relogged.
Let my also clarify I believe this to only be items place with the V function and not building blocks.
Indicators, map markers and Co-ordinates would be perfect! @Ane Could you suggest coordinates as a work around while the map is being worked on? This way if our maps get wiped (like they frequently do) we can have coordinates written down and just work our way home like that!
My first full building to be published to the workshop, I present to you the medium log cabin!
This cabin is only lightly furnished to allow the player/creator more customisation options https://ylands.net/asset/62
I appreciate any and all feedback, as well as ideas for future builds!
