The time between callouts is extremely long as I had it set that way so I could test vehicles with minimal interruptions. I will remove the return to station command from the ambulances, thanks for bringing that up. As for the fire units- there was an engine in that empty bay, but it kept crashing. I'm currently working on finding, modifying, and reskinning new fire apparatus. This beta was mainly to show progress is indeed being made, and also to show off the tons of police units I've added. There will be a CVFD engine 2 and then Brewer's Landing fire department mutual aid units (as seen by the light rescue truck). A BLVFD chief's car is currently in progress. Thanks for testing guys!
