Uh oh, I think I bugged it. (HeroForge Import Bug maybe?)

One of my Imported minis has a pretty broad visage. Spread wings and outstretched arms for intimidation, I figured he'd be super crazy scary big at 4x4. However, since I got him, his default size is set at twice normal, or 2x2.... even though the model is still default sized. Choosing 1x1 makes them scale down to half their size, the smallest size makes them super hella small! The maximum size, 4x4, comes off as being only 2x2 visually, even though they still have a large selection ring.

I know this option is still in Beta, I wanted to give a heads-up in case someone in charge ran into the problem and either knows what's up, or knows how to fix it.

This is not a bug. In discussions with HF the dev team decided that they wanted the scale of the base relative to the mini to match the HF preview as closely as possible. So if a mini is a bit large, it'll come over as a 2x2 TS-wise (you'll notice if you select the base, the highlight is different), but it'll have a 1x1 physical base and be scaled based on that.

Cheers, I'll save the answer in case other people need it.
