Hey trutty,
Sorry for the late reply. Ok, so this sounds off as we don’t cache anything currently other than save games and let the browser do the rest of the work. I’m thinking it’s possibly a new(?) issue with firefox. Did you say shipping still worked with Chrome? Do you have access to other OSs? I’d be interested to know if its a windows only issue or not. If you’re ok with putting a link to a build (shipping build please 
) I can try it on a few browsers/OS.
