Kept Battle Shard VIII on Reinforce

[wild bough]

After Completing the Permanent Battle Shard Slot Charge but not prestiging to unlock, I reinforced and had the Battle Shard VIII sitting in the red slot

I have backups just before and after if they are needed

You keep the batte shardregardless of it being in the slot or not.

but it is odd that you skiped the prestige step and it worked ok
