Underground Lab bugged, the challenge does not appear, only the mobs

Upon entering the underground lab during a betrayal-map, the event never appears, no evidence yet to be destroyed, only the mobs appear, no Syndicate members or Jun can spawn, this has happened maybe five times now, hoping this is regarded in the Betrayal-lag-fixes too.

The fortification event is also sometimes bugged, unable to destroy the gates leading into the fort.

Are you dealing with all the members of each encounter? Leaving some without dealing with them will prevent the next encounter from spawning in an area.

Yes, I do deal with everyone,trying to farm veiled mods! But thanks for the tip

I have the same issue multiple times. I also figured out the dealing with part that you always have to deal with them all and i do. But alot of them still bug out for me. Mobs are there event doesnt start and betrayel boys dont spawn.

I have the same problem.
For me it has only been with Underground Lab, but I am now up to three in a row (over two days), where the encounter don't start, but the regular mobs are there.

never had this problem last league, so there must have been some change that broke it :-(
