NAME: Upgrades cannot be claimed.SEVERITY: 2LOCATION: Forge, Inventory, Unit Upgrade Screen.REPRODUCIBILITY: ALWAYS.DESCRIPTION: Every time I try to claim an upgrade for any of my already owned cards, the server does nothing. Gold isn't taken away, upgrades aren't added to the list, nothing. Upgrades that I already own can be applied just fine, it's the claiming that seems to be bugged.SCREENSHOT: Unavailable.ADDITIONAL INFORMATION: I've also tried it with cards opened from a daily booster and it also failed to do anything.
