I got two Championship Jewels Token - Day 1

Hello,

I have logged into my account to purchase Championship Jewels Token - Day 1 (had 4823 IP), but I encountered error and restarted game client. After I logged in again, I went to shop and purchased a token without errors (had 4673 IP after purchase). But when I checked my inventory, I had two tokens. I forged them into 4 Championship Jewels and went to purchase another one (thought it was intentional and my IP didn't update), but it says "Daily purchase limit reached for this item.". Now I think I accidentally got one token (two jewels) for free due to some bug. Two questions: Was that intentional or will they be removed? Can I keep them? [slayer-jinx-catface]
