Two things!

I was so excited to see the new Volcano biome, but upon taking my warrior throdoma there a couple times, I didn't find any magma crystals. Are they just rare, or am I doing something wrong...? (Edit: Nevermind, I found one! Oooh, the molten etelia are pretty!)

The arrows that appear while moving the pet are also appearing on the far edge of the screen instead of around the pet. I couldn't get a screenshot of that, unfortunately.

Magma Crystals are guaranteed to drop from the biome-specific building. They may occasionally appear in chests, but they are quite rare.

Please try hard refresh on the explore page to clear the browser cache for the problem with arrows. 

I've refreshed several times and cleared cache, but they still appear in that strange position near the top-left of the page.

I'm afraid I can't reproduce this issue. Maybe it's platform-specific. Could you please tell which browser and OS you're using? 

I'm using google chrome, along wih a Windows OS. 

The arrows appear to be anchored to the sprite(move along with the sprite), but are off by a wide margin.

I cleared cache and the issue was resolved. Thank you.
