Addendum:
The only way to get followers to spawn is to add them as supports, for some reason SPT is preventing regular escorts to spawn on streets.
Adding
"Supports": [
{
"BossEscortAmount": "3",
"BossEscortDifficult": [
"normal"
],
"BossEscortType": "followerBoar"
}
],
"Time": -1
to the boss entry spawns the defined number of followers without issues every time. Same goes for the snipers - the only way to get more than one sniper guard to spawn is to add them as supports.
Can someone from the team have a looked at this? Is this intended behaviour?
