On my server we have the spawn % of the server turned down to 1% this was to encourage players to trade amongst themselves except minro problem not only are the shops spawning alot more frequently but we are also seeing them spawn in a solid wall instead of the usual random placement. keep in mind most of these are actually two shops in one sector. if anyone knows how to fix this or if this a known bug please tell me.
