Cacti is certainly a plural and I wasn't expecting it 😂 I don't know. If it was truly random then one would get the perception that it wasn't. 15k isn't that large of a list. Similar to how they had to unrandomize music selection when you want to play random tracks in your playlist. Truly random doesn't feel random for small sets. Maybe it is and just hasn't been going long enough to see those little oddities.
