I see. Hmm, I haven't encountered this exact problem before (I have seen a gray screen which means a room scene fails to load). 

I'll try and fix it this / next week. 

Care to add me on Discord? I'd like to send you a test build when I have one ready, see that it solves the problem on your end before I upload it to Itch. On Discord I'm:  Cosmic Void#8841

If you don't use Discord, please send me a DM on Twitter. On Twitter I'm: https://twitter.com/Cosmic_Void_

As soon as I have a test build ready I'll send it over!
