Fireman can't respond to emergencies

I have the same exact problem! It just cancels out every time I try to respond ☹️

I've tried a new save. In the broken game I once was able to respond to an emergency, there were none of the prompts I recieved on the new save, so something must have gone wrong early on.

After following the factory reset steps DO NOT FOLLOW THESE STEPS IF YOU HAVE A VALUED LEGACY I had to manually patch, my game wasn't being recognised, but the patch program reconned it was already installed, I told it to continue anyway. Unfortunately, even fully patched to 1.50, which it was before, the game cannot regonise my save. I've lost my legcacy ☹️

Although my original save had problems from the start, in my testing games I've noticed that as soon as I maintain the fire alarm, that's when I get problems. I've had this problem with two different sims, in fresh games based in Riverview.

It seems to be a problem that once it first occurs, continues to do so. For a few days I was able to ignore the alarm and Jacob would go to the emergency automatically, then the command started cancelling again. I ready on the Sims forum that you could send your sim to the plot and they'd start the emergency themselves and again, that worked for a couple of days before it started cancelling itself again.

Can anyone help fix the broken game?
