Last night we started a +15 SD and the affixes were: Tyrannical, Storming, and Bolstering.
Weirdly enough that’s not the affix combo that’s coming up (nor the current affix combo). The affix combo at the time of the run was Fortified, Spiteful, Volcanic, Prideful.
So obviously it was a weird run. But the runs (for me) before and after this were of the correct affixes.
