I have a Ice Breaker on my character I got from Xur weeks ago and another in my vault. The Ice Breaker in my vault is from before CE. So when I went to Xur this weekend and he could upgrade it I was excited. When I spent the coins it didn't upgrade however.. it reset the stats on my already upgraded Ice Breaker back to when I bought it from him originally D: Is it possible I could get my exotic shard back?
