Maybe it's too heavy?
I have a solution.
Make extraction press (and some other heavy things) liftable only by 2 hearthlings. Both have to lift it for it to move, and then it moves to the direction that is average of where 2 people who lift it click.
Would be great fun lifting them!
Str could affect to the speed like it does now but just sum of 2, maybe str could also make the press move a bit more in the direction of click, if the other lifter has less str.
Here is an illustration of what I mean!
