Sims 3 Pets Xbox 360 info requested

1) What is the Improved Subterranean detector/How do I use it?

2) How do I get my sim to return from the past. It glitched and other than turning on immortality and waiting it out is there a way to fix it?

3) Why won't the fire detectors work when my sim is on fire ( I have 5 placed around the workbench )? And why does my inventing skill keep going up while I am on fire? No complaints about that one really... Maybe some sort of cave man inspiration i guess.

4) Should I be concerned that my sim person that was never a pet has the option to howl along with music?

The list of glitches I have encountered can go on and on but let's just save some time. Am I being punished for the masses of sims being used as fertalizer in this games predecessors?

Welcome to our Forum, FlackRiot.

I play the PC version, but the fire alarms have never gone off when my Sims is on fire from inventing.  They only go off when the house is on fire.

The rest I'll have to let someone else answer because it doesn't sound familiar to me at all.

Try listing the traits of your Sim here, that might have something to do with the howling option. I really don't know about these glitches, or why they happen.
