No worries, i didnt realise it was such an exclusive list.
It's just nice to have an aug i can put on my guys without fear of just deleting it when i change the gear. Maybe not such an issue if the task was repeatable, especially this particular aug where it can be done really quickly....
Maybe repeatable tasks could be a thing? Much like the repeatable quests in T3 / T5?
Aug is lore so couldnt just stock up on them

Other tasks that take a while to do would suck to lose the aug when changing gear and makes it seem not really worth doing, other than to see the content / have something to do, so being able to move it for free is really nice.
I looked up the treasure goblins, and if theyre only GM spawns its very unlikely ill ever see one. I think the chances of me being online at the same time as a GM are very very slim
I think the only source of distillers for me is either the christmas event with the uh.. collection task i think? but that's obviously only around for a very limited time. Or the haggle baron which is just super expensive. So i dont really have any sort of source of distillers to keep these one-time augs.
