So Magehand can be cast in that wagon cart? Or did you cast it on a crate or ground?
On the ground is fine ...
I wonder how did you people managed to miss it, i writed this tip to every single topic about "unreachable objects" i found since day 1.
With the unreachable potions: Eventually it is possible to throw them to other Characters to avoid breaking them?
Nope ... if you throw potion "at someone" it breaks too ... and your target will imediatly take its effect.
But once you can throw it, you should be able to relocate it by simply draging.
