Olaf Not Immune
Olaf just is not immune to crowd control effects during his ult. When facing other glacial comps he constantly gets stunned

I just experienced the same exact bug in my last game. Even the text along the lines of "Can't be disabled" pops up, but he still gets cc'd. And yes, it only seems to happen against glacials from what I've seen, maybe it's intended? If so, it needs to be specified.
The animation shows he is freeze but actually he is still hitting and doing damage.
