Seabed Frost Town - Normal: Bugged drops?

[c2df1y]

Trying to get Golden Corals to evolve a card, and this is the easiest place to get them.

However, all of my Golden Chest drops are coming out as Golden Seashells, instead of Blue / Golden Coral... What's going on?

Edit: Also, I'm getting almost entirely Golden Chest drops each time I run it, have the Normal Chest + Golden Chest rarities + contents somehow switched?

Edit: E.g, this is from 2 Normal + 2 Golden Chests drops: http://i.imgur.com/0mbIoOP.png

Hi c2df1y, the drop rate of seashells in Seabed Town - Normal are designed to be much higher than that of corals. You can try to battle the Seabed Frost Town - Difficult for corals have a much higher drop rate in that map.
Thanks for the report. I will forward the golden and brown chest drop rate problem in Fun Wednesday bonus map for our Dev Team to check.
