I wanted to get a donkey to carry some items for me. When I found one, I tried to feed it carrots so it will be easier to tame. The feed button showed up, but when i clicked on it, it did nothing. When I tamed it, I couldn't open the donkey menu while sitting on it. I got off and crouched, and opened the menu to put the saddle on. When I closed out, the saddle disappeared. I opened and closed the menu again, and it reappeared. I attached a chest, but I couldnt access it by opening the menu.
Recreate:
Spawn Donkey
Try to feed it
Tame it
Try to open menu while sitting on it (The button dosent show up)
Get off
equip a saddle by crouching
equip a chest
open donkey menu
No chest area!!!! who's going to carry all my seeds??
(win 10, survival) Same issue I think: I had a tame donkey and a mule from before the 0.16 version. They both had saddles, only mule had a chest. Now neither saddle shows up. When I right click the donkey, "saddle equipping sound" plays, and the saddle shows up in the inventory. After that, the saddle shown on the donkey as well. The mule however, seems to have lost the saddle entirely, but the chest area is visible when I interact with it.
