Issue description:

Steps to reproduce:

1. attempt to place lava on top of heat generator
2. the lava goes through it

Version (make sure you are on the latest version before reporting):

Forge: 34.1.25
Mekanism: latest dev

Its a feature to place lava inside a generator. But it should float like water...

Yeah pretty sure this is an intended new feature.

I noticed that this happens to the infuser too, did not know that this was intended

going to close this issue now

Ya it is intended, it is now possible (by lava logging both the generator and the cables) to have "seven sides" be "adjacent" to lava for the heat generator instead of just five.
