Beefalo loses speed boost coming up from the cave

This happens to me aswell, my temporary fix is turning lag compensation off and the permanent one is just spending one use from the saddlehorn to take the saddle off so its speed resets.
From what i can understand its the saddle that's bugged, when i look at the item itself using the beefalo widged mod to display it while im riding its durability isnt shown, and the same thing happens to items with skins stored on my backpack when i go up\down stairs. So i'll just assume it's the same bug and that it'll get patched soon.

Beefalo don't get a speed boost with canes or roads in DST. Only the glossamer saddle gives the speed boost.
