I compiled godot using the code at master branch in github (right now my version says 3.1.dev). When I try to install the templates it gives the 'error getting list of mirrors' message. I guess templates are only released for stable builds? Can I use stable versions' export templates on the custom builds somehow?
How can I find export templates for the custom builds?
Never mind, I downloaded and installed the template manually from here: https://hugo.pro/projects/godot-builds/
