Update: The prices for Drone Fusion are meant to go up each time you reach a new region. However the last few regions we missed raising the price and it was fixed this last time. Sorry for the confusion.
Situation was looked into, it appears the player was suffering from a bug and has since been corrected. Their Defense Power should be showing correctly now.
Because it is still in maintenance and you need to wait. Slummer mentioned it was still in maintenance and I replied saying I informed the team and so they can look into the situation. Please be patient.
