Beacons...oh Beacons :(

[iKonjo]

I'm not sure if this is the right place to post but... 
Beacons for the key for the Vay Hek mission are they bugged?
I ran Nuovo for about 5 hours straight with my desecrate build Nekros each run for about 40 minutes 
and all i get are Delta beacons. I haven't seen any other beacons. Do they still exist? :(
If so which mission is the best to farm?

[Vordreth]

To farm Kappa, Omega and Gamma beacons go to a Hijack mission with one Trinity and one Nekros. Let the core stay between the last two rooms and let Trinity heal it when it's with low health.

That way you can run the mission the time you want because the level of the enemies will not increase.

They just upped the spawn rate for prosecutors, but you wouldn't know it. It's a PITA to farm for Hydroid.

Did a couple of twenty-round runs on Casta and only got Delta beacons. I think something's bugged.

Thought they buffed the drop rate of these?

 

Can't offer much help for drop rates besides suggesting survival which is what worked for me. Just extremely bad luck.

They changed it supposedly so the first spawn is guaranteed to be a delta beacon... but instead ALL spawns were delta beacons. Which I think is unintentional.
