Hello, I haven't met this bug, but I do encounter weird, green coloured things in the game, so there's definitely some kind of error on my side. I'll try to correct this as soon as I can, thank you for the feedback.
One of these days i've checked on the project, and I had this problem in Chrome. In FF, it was fine. The interesting part is, that today, it worked well, currently I'm planning on restarting the project, I hope to watch out for stuff like this.
