Not sure 100% that this is a bug per say but it is still an issue that might need to be address.
Tonight when I was attacking in arena I was attacking near the end of payout to hold rank. I was first place when I selected the team I wanted to face (3rd) then hit battle. Once the battle ended instead of being first place it said I was 5th place? Since there was no time left before payout I could not attack back to first. Not sure 100% how this happened but my guess is the match someone was opposing me must have posted the split second between me selecting the team I wanted to face and when I hit battle. Since there was still 5 min left I had plenty of time to beat the team in first however since I was in a battle assuming that I was in first and will be til payout I had no clue that my rank had changed. This needs to be addressed so that when I select a team to battle and hit battle if my rank has changed that I am notified that my rank has changed. I have seen that before but usually I cannot battle the team I attacked because there rank is further ahead than I can battle but nothing was displayed this time. Please look into this.
I have expressed my opinion on why the set time is bad that can be seen here but this is just another issue why: Arena Payout
