I'll check the AIW to see how many garages/pits there is available..
EDIT: Ok, there's 16 spots available with 2 slots shared per team, normal practice. Slots 11-16 are different from the rest. I didn't find anything wrong with the pits themselves but the garage positions looked a bit close to pit positions. I don't know if that affects in anyway since garage positions are not used when you're on track, it's just a reset location for each individual car. I'll try to remove slots 11-16 and share slots 1-6 with 3 cars.. Testing now...Come on, start already...
EDIT II: The return of the Edit: Ok, looks all right, the game loads with 26 AI drivers fine and none are located in fornt the closed garages.. The trackbuilder really hasn't thought this one thru, there is no reason to use 11 garages when F1 has 12 teams with 2 cars each and the game default is 25 slots (or 26 with 13 slots x 2 ) and the building has 15 garages.. I know it looks cooler when some doors are closed, i use that in Cicada too but i made sure that there is enough available open garages for all cars...
Fortunately the game can use even one pit/garage shared by all cars, the max available slots is defined in the grid/teleport... I'll test if the AI can make it thru the race with forced pitstops, if the AI makes it then we should have no problems, i'll report it in the EDIT III: The Revenge of EDIT.
EDIT III: The Revenge of....: Ok, 25 AI made it thru pits without a hitch. Should we still test it with human drivers? We need at least 12 drivers.
