A hearth at the core? how cute :3

Maybe it was always there but I never paid attention to it, but really? a hearth? why not a golden coin at least?

I actually spent forever looking for a hearth in that picture...

lulz, so you telling me my PC takes forever to load the level so i cant see that bucket before an ally destroys it?
If it weren't for that hearth i'd never know there was something there

It's in the 2nd RT level and some of the clockwork levels near the elevator down

I looked for the hearth for a while too.
@OP, you mean "Heart" not "Hearth". You made the same mistake multiple times, so i'm assuming you werent just making a typo.

All I see are a bunch of emergency flares and a ramp. I don't see a hearth.

i didnt see it at first but now i do

That's just a bucket of nuts and bolts your allies kicked over on their way past. Gives random loot like any shrub or torch.
