So I just hit level 50 playing on very hard and I just recently started doing the more important main quests. I completed building the relay with the railroad and I just started Liberty Primed for the BOS. I've done synth retention for the institute and warned the railroad about bunker hill because that's who I've decided to side with for the endgame. My question is why am I only getting radiant quests for the minutemen? I thought that I would be getting some quests involving the institute from Preston or Sturges but all I keep getting are kidnapping and settlement quests, would it be different if I decided to build the relay with them and if so why can I still get institute missions from BOS am I missing something?

Nope you get only the same quest from the MM ,i build the Relay with them didnt change a Thing ^^

Even just walking by Preston or having Freedom Radio on gives you a MM radiant quest. But with RR and BoS, you have to actually speak with the quest givers and accept their radiant quest.

There are radiant quests for the Brotherhood too. Talk to Rhys and Haylen back at the Cambridge Police Station. You can get radiant quests through P.A.M., Tinker Tom, and Drummer Boy at the Railroad.

Yea I've been doing those radiant quests also but I was hoping there would be missions involving the institute given by the minutemen at some point
