Okay, that’s bizarre. It doesn’t seem like a bug though, it seems intentional to get the thing that needs scaling to be scaled correctly without interaction with the parent.
Yeah I think this is just going to take a massive amount of playing around.
Or… You could make a smaller “Alternate” version of the characters. Have another, smaller capsule parented to the root, with another, small skeletal mesh and activate those immediately before disabling the larger counterparts and vice versa?
