There comes a time in every seyan's life (or some of them anyway) when they look at the /data command and realise that they have missed a lab seyan shrine and have no way to go back and get it.
Out of the goodness of our hearts and to stop in game stress and depression, it is now possible (at a heafty cost) to request the missing shrine flag be reset for you.
Note that you must have passed the lab to be able to request this. This is the cost per shrine and you must be able to pay all 3. Exp can go negative but you must have the gold and plat available.
Cost 100k exp AND
Cost 100k gold AND
Cost 2k plat
Some may consider this to be harsh but some of the suggestions made were more severe.
Note: Only gods can reset seyan shrines.
