Tyrants's Skull disappearing / rolling back every time I purchase it

Generally, you should include:
What went wrong?
Tyrants’s Skull disappearing / rolling back every time I purchase it. I’ve purchased it 6 or 7 times now. Within 5 minutes it disappears, returns the currency, and places my previous relic back on my character. Its a different Tyrants skull every time i purchase it as I see the +minion skill change, as well as the implicit mods change rolls. I needed 4 additional Primordial Shards to purchase the relic and it has now duped the 4 I purchased. I had 15 the first time I purchased the Trex relic and now I have no relic but I have 19 primordial shards.

Do I need to include log file to investigate this? I’ve re-logged. I’ve restarted the game. I’ve changed zones. I’ve purchased tyrants skull in town and also within an echo. It disappears each time.

Update 1: The 4 primordial shards I bought to be able to purchase the Tyrants Skull keep re-appearing in my inventory. It may be visual but they are taking up inventory slots even when they aren’t showing in my inventory. I now have 50 primordial fangs up from 15 because they keep reappearing in my inventory after I transfer them.

I was having the same issue trying to buy Velocyn’s Jaw. I found a fix by dropping the currency that keeps showing up in your bag on the ground and picking it back up again. It seems to be a bug where when buying the currency it is not registering that you have it until you pick it up off the ground. Hope this works for you.

This worked. These shards go into your inventory when purchasing from new vendor and then you have to click the transfer button to deposit them. I did this to reach the number needed to purchase Tyrants Skull. It would disappear each time and then the 4 shards I purchased would reappear. Once I dropped the shards on the ground and picked them up (which sends direclty to your keys tab) I was able to purchase Tyrants Skull without the item dissapearing. Thank goodness it gave me a +3 like the very first one I attempted to purchase. Thanks for the help!

I meant to add the reply below directly here. Thank you for the help!
