I had around 250 flash grenades but suddenly they disappeared.
I was attacking since we're chaining and could use them for a while and then suddenly I couldn't, checked to see what was going on, they were gone.
It's gone on both mobile and computer and I've tried incognito mode and it's still gone. I tried clearing my cache, still gone. The only other idea I have is that I accidentally sold them, but that wouldn't make sense since I could use them for a while, and I can also not find them in any recent logs.
