Teleport Doesn't Randomly Choose Destinations with Same TID

[Razumen]

So I was testing out some simple teleporter varieties as an example for someone, and I found a discrepancy between how GZDoom currently handles the Teleport (70) line special compared to vanilla (I used Chocolate Hexen for vanilla testing so it SHOULD be accurate).
In CH, when the teleport special targets multiple map spot destinations with the same TID, it randomly chooses one of the destinations to send the teleported actor to. But in GZDoom, it will only use the first destination it picks and send all the actors to that one, ignoring the rest of the map spots. I double checked and the wiki says that CH's behaviour is as intended: https://zdoom.org/wiki/Teleport.

To recreate it, walk through the third plague from the left at the map's start. Make sure to attack once to wake up the monsters.
(Tested on GZDoom 4.14.1 and Chocolate Hexen 3.1.0)

Can you confirm this map specifically is randomizing in vanilla Hexen? You're using map spots which, according to the teleport code, was an oversight on MAP10. You're supposed to be using teleport destinations for the randomized behavior. If this also works in Hexen then I'll update GZDoom to support it.

Map spots are indeed not randomized and support is only for backwards compatibility.
