Strife chests stop spawning

It seems there’s a fixed amount of chests that can spawn, after which they will stop appearing even if you’ve opened them all and made them disappear.

Resource nodes as well.

Also, after a while, I start experiencing random slowdowns where the realm is completely empty until I walk around for a while (while the game gets progressively slower until it stops completely and then goes back to normal and the enemies spawn).

Edit: Eventually the slowdown became permanent and no more enemies spawned. Could this be related to the other Strife issues I reported last month?
