Playing in survival mode with cheats turned on:
/summon EntityHorse {Type:1} command ALWAYS produces a horse. Different colors, sometimes even babies, but never the donkeys I expect. {Type:2} also gives me a horse, not a mule. {Type:0} unsurprisingly also gives me a horse, but that's expected..

You possibly have to add location vaules before NBTs. So command have to be "/summon EntityHorse ~ ~ ~ {Type:3}"
Please provide exact commands used
