Usually, we could choose one of the three Severed Threads pacts with the Weekly reset on the Quartermaster in Weaver’s Lair and then do the related tasks. The NPC even had an option to change the Pact during the week (for testing purposes).
In the actual Build 55288 this is completely missing on the NPC, and I think it causes a complete lack of these activities for the moment, and players can also not progress when they choose the related Worldsoul Weekly in Dornogal.
Looks like it got hotfixed and is available again.
