I had an unused Key and then I got another one by accumulating influence. It showed me getting the Key but it’s nowhere to be found. Really sad about losing access to another Spellslinger.
I had just obtained a second key tonight and when I went to unlock another character the icon only showed me having one key. I chose the character and was hoping that it was only a visual glitch but I now have zero keys. This might have been the second time this has happened to me. I wasn't paying that much attention the first time so I wasn't absolutely sure and didn't bother to log anything, but this is definitely happened to me earlier tonight. Very frustrating.
You can't hoard keys? That's good to know, and also extremely annoying. Once you've got a few working decks, you want to be able to save your key for when a specific Spellslinger quest pops up, so that you can unlock that Spellslinger and complete the quest.
This also happened to me. It's incredibly frustrating considering these keys are so hard to obtain. Can we get compensated for this? also, they just need to fix stuff like this or lay it out in detail you can't have more than one key at a time.
