Re-rolled has always been messy IMO. Player count causes issues with the faction specific models as not only is there more playable countries (ones that aren't specified in .vidx due to the base game and most maps reading 8 players) but the changes in faction orders 0-9 when compared to the vanilla 0-7 throws off all .vidx files as well, leaving nearly everyone using models they wouldn't normally be compared to any other 8 player map.

When you say "hosting" I'm assuming you mean multiplayer? I can't fix multiplayer based issues as 9/10 of them come from the game itself taking too long to load nearly half a gig of mod content as you open the construction/research trees, on top of anything else you happen to be using. general rule of thumb is if it works while playing solo, it's a multiplayer issue. Unfortunately you'll have to default to detailed earth for multiplayer if you want occupation features until I get these new "detailed" maps out.
