Yes it does look silly on such a huge lot. Well I think this is something similar so what I did was I bulldozed a 60 x 60 lot and placed a fire station there. Remember a couple years ago when certain rabbit holes in Lunar Lakes and Monte Vista where no longer open to Sims because it was 3 square tiles or less towards the edge of the lot (although that glitch was later fixed in a patch). Long story short after spending time testing different situations it turns out that this glitch is more then likely a lot space issue. I was flat out determined to figure out how to resolve this matter even if it was just temporary. It's been two years since I've played the firefighter career the best one in ambitions in my opinion but as a lot of you know or have experience there is a horrible glitch where the emergencies cancel out and your Sim is not able to do their job.
