I'm still softlocked out of a mote of light ever since the issue arose with the boss in the Blooming. The triumph still says I haven't killed it, even though it's likely the one I've killed the most. I have all 16 other motes, from the other bosses and collectibles- I've placed all of the travellers in the Pale Heart tower. I just don't know what to do, I've been locked out of this quest for months. Any tips?
