While I recognize the focus of this testlive build, some pets still have incorrect growth chance percentages. I only tested Blue Ostriches, but 8 in a row had 40% in agility. Somehow, for a fighting animal this just seems, well, wrong. (spawned in singleplayer admin mode)
I could test more, but refer to @Tharl’s extensive testing on both officials and in solo.
As of 4-9-2020, horses had their Agility growth % un-nerfed. Still no word in the forums if all this is intended or not… so place yer frozen horses now while you can! The other bugged pets seemed unchanged.
