Format: Android (latest build)
Issue: I have multiple identical gems of equal levels yet am unable to combine them (instead of being listed as 2x ‘X’ on a single line they each have their own line in the inventory.
Note - may or may not be related. I only noticed the issue after multiple gem level up & gem level down procs from pandemonium tokens.
Edit: It does look like it is a pandemonium token level up/down issue. It appears not to activate the ‘are the gems the same’ check and neither stacks them correctly nor makes them eligible for combining until you exit the game.
