Artwork won't align to centre of artboard

[RunForestRun]

I can't get my artwork to align to the centre of an artboard, it keeps happening with different artwork. I have some shapes all selected on the same layer, align to artboard selected, not align to selection. It throws the artwork off the canvas. It feels like a position where the canvas may have been previously. It feels like a bug but maybe I'm doing something wrong.

Do you only have one artboard when you look in your artboards panel? Just want to be sure it's not centering on another artboard in your document. If it's only one artboard, have you restarted Illustrator? If that doesn't fix it, you can reset your preferences and that may fix it. Hope that helps!
