I contacted a gm and they directed me to post this here. I encountered a bug in phase 4 of the beta that made the cracked materia exchange at the Calamity Salvager NPC very confusing. When trying to sell or exchange materia I would get one of two messages: "Exchange 5772 the fire crystals for 1 the __ Materia" or "Exchange 5772 the gil for 1 the __Materia" . I was trying to find the option to exchange the cracked materia in my gear for the Tomestone currency but it was very confusing when I came across the aforementioned buggy dialogue. I ended up exchanging the materia melded in my gear for new materia and then trying to see if the issue was resolved and to see if after the exchange it might let me trade the newly melded gear for the tomestones but I had unknowingly stumbled across a point of no return in the cracked materia exchange process.

Everything seems to be working fine and the npc clearly states the correct exchange rates and currency now in early access. My problem now is that in the confusion my materia has already been exchanged in the beta and progress was saved leaving me with no option to do the very thing that I wanted to do in the first place which was exchange the materia for Tomestones.
