Hi guys - we identified all the accounts that accidentally had their Defence reset. This was caused by an unexpected error from looking at resetting the pures affected by the XP bug a few weeks back. We can confirm that 24 accounts were affected and that over half of them have already been fixed. We'll reach out to the remaining 10 players via inbox message and return their Defence XP as soon as they are available (they need to be online for us to do this).
