What were you expecting to happen, and what actually happened
I think this might have to do with the Rare quality Savior’s Helm. It says it creates 2 Big V gems at the start of a battle. Unfortunately it seems that it displays as a different color that it is. Perhaps it creates a Red and a Blue but shows both as Red until the “fake red” moves. You can see this with the red gem not matching and then turning blue after it drops down one.
How often does this happen? When did it begin happening?
It happens fairly often and makes beating stages rather trickier than they should be
Steps to make it happen again
Seems to happen at gem creation at start of battles.
