Interesting that it works in safari and not chrome.
I lowercased all the names and the flames still work on desktop, but appear as black on my mobile. I have also added the original skin file,just habit that it was encrypted. Nothing special in there, I just added a custom hotspot for my main vr tours and the do_crop_animation function.
I have left work now, but will pick back up on this in the morning and create a stripped down version to see if that helps.
