Hi everybody!
I wanted to let you know that we have a visual bug in the newest version of the game (11.0.0.167828) that may cause you some concerns.
When you click on the energy objects (toilet/bed/shower/bath) it shows that it gives you just the base amount of energy, without the energy from supporting objects.
This is a visual bug, your Sims will get the correct amount of energy, with the energy from the supporting objects added to it.
To know what the correct amount of energy is, tap on the energy bar for your Sim and it will show you there.

We're sorry about this and we're working on fixing this bug.
