Thank you very much for all those confirmations and informations. It helps a lot so that I can give advice to newcomers.

When you make the ghost building parts invisible for non-tribe members, this also has an impact to keep in mind: When new players start building their first parts and have problems, I have several times visited them and given hints about how to move and place the parts. I would be unable to do so when the ghost parts are invisible for me.

What would the impact be if tribe members can see them transparent but non-tribe members can see them maybe non-transparent but simply in e.g. light blue colour so they can distinguish between built parts and ghost parts? Would that help in reducing the lags?

Maybe this could be tested on testserver when all the other planned updates are done? We lived so many years with the lags caused by the ghost parts that for now the knowledge about the reason helps, too. Thank you very much!
