We investigated your transactions and the records from your trades and account actions during the event.
After looking at that day, we are unable to find any instances where after your trades you ended up with 8 seals.
We do see that your repeated activity shows you submit your remaining purity to the bar after your trade, but in no instance were we able to validate your concern.
Can you please continue to monitor and provide us additional info if you see something occur again that doesn't make sense?
Thank you for your understanding.
