Hi there. Before trying to collect the worms make sure you interact with the desk/console at the beginning of the dungeon in the secret wheel room to pick up the latest research report and also enter the correct code at the wheel. If you don't pick up the report, the game will not register your interaction with the worms. If you're doing this and still not getting progress, then you may be picking up worms from a previous step and not the current one, which won't count. Check your current quest step against a guide to be sure which 3 you need to interact with. If you can't interact with a worm, make sure you're on the correct quest step and try being the fireteam leader if someone else is. If the quest still isn't counting the worms, then you would likely need to progress the quest on another character.

Hey there, adding on to what GrumbleBeans has already said, if you've been sherpa'd through previously and collected worms you may not have had access to under normal circumstances, it sounds like you're just picking up duplicates rather than new worms not being registered. For example if you look at your Laboratory Inspector triumph progress in something like [url=https://bray.tech/2/4611686018452981924/2305843009271770030/triumphs/node/4011083713/2196753074/2009673092]Braytech[/url] (link to your stats provided), you can see you've picked up two duplicates. From what I understand, the worms are presented on the triumph as follows, Before 1st encounter: #1 Witness (Set 1 - 1st) - below the bridge near the start, #2 Hive (Set 2 - 1st) - while dropping down some platforms towards some mud after beating the two subjugators, #3 Guardian (Set 3 - 1st) - use an invisible platform in the '+' shaped room where you crawl through a waterfall. After 1st encounter: #4 Give (Set 1 - 2nd) - in the huge open chamber full of dread, #5 Grief (Set 2 - 2nd) - a little after the above section, after a drop into a room with two sloped edges, there is a ledge that lowers to reveal the room, #6 Knowledge (Set 3 - 2nd) - at the top of the spiked rolling ball section, After 2nd encounter: #7 Darkness (Set 1 - 3rd) - top right in the lens puzzle room. #8 Worm (Set 2 - 3rd) - after the Lockset boss, after the long drop down, it is to the left in a room with a dead worm in front of a massive gate, #9 Fleet (Set 3 - 3rd) - after the lens room in the room where you fight the Subjugator - descending ledge at the back wall. You are missing #5 and #9 on the triumph, so #5 and #9 above - apologies if the above is inaccurate it's about as accurate as I could tell. You might just have to do what I did to find the one I had missed, do all of them over again in turn until one registered (it was the 8th here for me).
