I play on switch and it says I have 90 mythic prisms. I didn’t buy anything last season so I should have 80 or so prisms, yet it wont let me purchase anything. I went onto my PC to see if maybe I could buy it on there instead yet apparently I have -10 prisms? I don’t know where my prisms went nor do I know what to do to fix it 
I tried logging out of all accounts and trying it that way but it still says -10 and 90. I just wanna buy the Lifeweaver mythic bruh
