Hello, this is GM Lulu.
After Ver 1.9.4 updates, we’ve confirmed that the summoners obtained through Summon shop are being summoned by Lv.10.
The development team identified and corrected the cause of this bug through error fix updates.
And we initialized the level of the summons which were obtained at Summon shop through last updates.
In addition, the Summon Growth Stones and Summo Pieces used in the initialized Summons were returned to the bag after the updates.
※ Returned rewards will be sent out in order and can be checked in your bag.
We are sorry for your inconvenience.
