My First Pet Stuff failing to download?

Hi! I just repaired my game, every pack downloaded except for My First Pet Stuff. It just fails, every time. I owned it before and have owned it since it came out. I only do not own a few packs: Batuu and all appvalley tutuapp tweakbox kits minus Blooming Rooms and Little Campers. No idea what happened. I did just install some new mods, specifically Zerbu's All Worlds are Residential and the corresponding Venue Changes mod, but why would this fail my download?
