Fatal Profile Retreival Error

Seems like you have some unexpected character in one of your inventory tags. Can you PM me your profile json?

It might be an issue with escaping characters in tags.

Yep, bad tag name. Search you profile to "Tag" keyword and either delete all tags or rename to include only Latin characters and numbers. Example:

"Tag": {
   "Color": 0,
   "Name": "9x19 Ammo"
}

Before you delete the offending tag, I'd like to see it's contents first. If some symbols aren't being escaped when setting tags, I'll want to fix that to prevent this issue from reappearing.
