Treasure chest picture but no rewards after winning?

[dapper jay]

On a few occasions after I've beaten an enemy in the overworld or in a dungeon, instead of the usual after-battle screen where I get gold/shards/cards, I just get a picture of a treasure chest with seemingly no rewards. Picture attached. Is this just a random chance of getting nothing or am I missing something? It just now happened when I beat a Demon.

depends on what world you're in. If its in realm of legends or core; its a bug. In core there's definitely a few chests like that which have been bugged like that forever.

If its in old border; there is a % chance that this happens as not a bug
