Colossus' model scale-up not matching patch notes?

[carrotoniii]

I went into Sandbox to try the new Colossus item, but the model scale-up doesn't really match the 10% on the listed changes. Plus, it doesn't seem to do anything to the models? I don't notice a camera shift on any heroes I've tried, at least.

LITERALLY UNPLAYABLE

the item tooltip says 1.2% instead of the 10% in the changelog as well
