Mission objectives/completion laggy


Since the Landfall update the mission objectives became very laggy. It takes sometimes up to 20 seconds for objectives to be registered correctly. This behaviour is especially krass on Himfjäll.
I observed the utilization of my hardware. My CPU was at about 40-60%, I still had about 7 GB RAM free and the GPU was between 80% and 90%.
The clip below shows one occurence of that.

Steps To Reproduce:
Complete a mission objective.

Images / Videos:

Host or Client:
Both == solo

Players in your game:
Only Mathilde.
