That's odd, how did you die in the game? Most likely related to that, then I can take a look.
With TF gacha artifact you refering to the Puple/Pink Crystal that gives a random tf? Or which one?
Defeated in battle, simple as that. As for the TF gacha, it was the artefact that gives 2 TFs and 2 TF items. Also found another potential bug, where the green crystal that boosts healing does not start tracking floors cleared until after you obtain it. This might be intentional, but previous versions had any floors cleared take effect immediately.
