So... Just got a js alert message saying "out of memory... etc." Refreshing the page worked, but I have 64 GB RAM, and 8GB VRAM SLI... Happened when choosing to battle stage 1-3. I understand what this means but it is certainly not my system. If you are a dev and have a question, simply let me know as there is an apparent memory leak. (Google Chrome Version 60.0.3112.101 Official Build 64-bit). Cheers.

Thank you for the report! The team is aware of the WebGL memory issues and is working to resolve them.
