Having the same issue but several husky weed plants and dandelions are also refusing to respawn. The two near the first ranger station/outpost respawned around four times since I started the world but after about 20 in game days they stopped. Now I'm on day 49 and haven't seen any husky weed respawn or the milkweed pods.

Buggy went down and I respawned at an outpost. It forced my buggy into the nest and gave me a 3 min timer on both buggys in the summons menu with an empty red box at the top of the screen where the revive count down timer usually is. The buggy that went down had a lock icon on it in the menu and has disappeared from my nest. But the other buggys timer is stuck at 0:00. And can't be resummoned from the nest or the menu. I've dismissed the one with the lock icon and I assume it's just gone but now I'm stuck unable to summon any mount.
