Please provide us with step by step explanation how this bug happened so we can attempt to replicate it. If it's complex, please include screenshots where possible:
I was exploring in celestial explore and started a fight with a cluster octopus, ended up closing lioden for a bit. When I reopened it I was taken to the battle screen in the shrubland zone but still fighting a cluster octopus. The enemy's art did not show up, but other then that and being in normal explore, nothing else was broken/buggy/off
