Reroll Counter Bug [CLIENT]

Ok, so I logged in last week for the first time in over a year and it said I had 2 aram rerolls. That's probably right as I played some of that. I played custom games/practice games all by myself to well... practice. :P I noticed my counter said I had 0 rerolls on Saturday. Then I played 3 co-op vs. ai games and logged off for the night. Yesterday morning I logged in and it once again said I had 2 rerolls. Played a couple more custom games to see if I could do anything with Nautilus and Shen and it went back to 0. Logged on a little bit ago this morning and it's back to 2. Custom games might be messing with it? Idk.
