Re: TheSims 4 - My sim energy bar doesn't decrease, it's always full.

@sanooksukjai

Is it only the energy bar or all bars?

All bars:

Have you perhaps used cheats?

Hold Ctrl+Shift+C to open the cheat bar, then enter testingcheats true

Shift-click on your sim, and there should be an option to enable mood decrease

Only energy:

Might your sim have one of the treats that make then not have to sleep? Check your traits and see if you can find any trait that makes the sim less sleepy. Do you have them?

Regardless:

Mods could cause this.

If you have mods/cc in your game, remove all of them to see if the game works better.
For example, move the mods folder from C:\Users\Username\Documents\Electronic Arts\The Sims 4 to your Desktop and start the game.
