Worried statement: The file you pointed out was absent in the override folder. I recall that one of the mods' instructions said, that it modified globals.jrl, but I forgot, which one did it. I am, however, certain, that the mentioned mod was present in the "compatible mods" list under the corresponding thread.
Nervous query: So is there a way out of this without reinstallation and possible loss of the saves?
EDIT
Answer: I just used the merger tool found here to merge two global.jrl's in the Override folder (the mod, that edited it, made a backup). I am still uncertain, however, whether the quest itself became playable is still unknown; the journal entries are all right now, though.
EDIT#2
Statement: Just now I returned to Telos and nailed three HK's waiting in the docking bay. The journal updated. However, as I understood, certain conditions are required to enter the factory (besides killing two additional packs of droids) - I stumbled upon a line saying "You cannot enter HK factory willfully, it should happen naturally along the story" (or something similar). Does this mean the factory is accessible only during the return to Telos right before Malachor V?
