For some reason even though i have set up the tavern correctly with beer and tables/chairs i dont get any customers, the book says i have had customers (300) but not sold any beer? i dont know what to do?

Hey! Do you have a faucet filled with beer which can be accessed by the patrons? And do they come and just leave or do they not appear at all? If they don't appear but did before, could it be that some path to your tavern got blocked by respawning stuff like bushes? If so, you could have a look at the guidepost object: it allows to place new customer spawns on the map's border.

I have a faucet filled with beer and they dont appear at all, i will check for obstructions. I wasn't expecting a reply so soon Thanks!
