Don’t have one right now.
What you were expecting to happen, and what actually happened:
After using fully upgraded +10 Flame Soul in Invasion battle, battle won’t continue. Some gem"slots" are empty and I guess game waits for those to fill up again. Only option is to retreat or quit. Lost 2 sigils for that bug
How often does this happen? When did it begin happening?
It doesn’t happen every time, maybe 1 time in 3 uses but I haven’t used that much that weapon so I can only verify that it happens from time to time, not every time.
Steps to make it happen again
Use fully buffed Flame Soul in Invasion battle (might happen on other battles also). Not tested on PC so I don’t know if it happens there too or is it just my device.
