since the changes to the chests to stop farming by despawning the chests immediately, this triumph is no longer tracking the chests correctly, i have completed all 3 types of "timed deepsight puzzles" (torches, runes and platforming) and none of them increased this triumph, whereas the same chests increased the triumph before the changes made to them. i assume this is happening because the triumph only tracks that you have opened a chest, AFTER the new addition of the game despawning the chest, which because the chest is despawned, the triumph cant detect that you opened the chest, essentially the new mechanic has cut into the timer that the tracker runs on.
