Follow the advice I posted above to prevent this.

This doesn't work. You can't do anything; go to the bathroom, shower, use the phone, eat, etc while the fire is going. I tried to wait it out today. It burned for an hour and a half real time. I had to cheat to keep my sims from starving. I eventually had to restart my game because it was obvious the fire would never go out. EA needs to fix this. Why can Sims not call the fire department? It's ridiculous.

Yes you can. If you are on fire you will have an option to "extinguish self" when clicking a shower. If you are not on fire this option is obviously not there. The option to put out the fire will be there when clicking the fire unless you yourself is on fire which makes sense.

@KateDunn1& @nikolasgaming123, what @jpkarlsen suggested should work for you. If it doesn't then maybe your game is glitching. In that case you can either try a "cheat" to reset you Sim, or you can exit your game without saving. If you exit your game, you will loose all progress since your last save, so if you haven't saved in a while, you might try to avoid this. In that case you can try the cheat by pressing "Ctrl" + "Shift" + "C" to bring up the cheat box and in the box type "resetsim First name Last name. So for example, if your Sim is Bella Goth, you would type in the box "resetsim Bella Goth" and press "Enter".
However, please try what jpkarlsen suggested first!
