Problem description See attached screenshot. When the brick is on the right side the energy blocks are not in the objects until heat is added.

I was able to immediately reproduce in the latest version by simply turning on Energy Symbols and moving the iron block:

Additionally, the olive oil or water beakers aren't present on the intro screen!

I looked at 1.4.18 and neither issue is present, so it seems like a significant bug was introduced in 1.4.19?

Apologies, I must have mixed up some behavior. I'm able to reproduce after adding the qp "?elements=brick,iron" in both 1.4.18 and .19 (and other recent versions). I'm not sure when this was introduced.
