🪲 Known bugs

On Fennec (Firefox for Android) pages sometimes refreshes and the model is gone Workaround: Go to the previous page and reload the model
Simplify setting often does not work properly (good news: you don't need it!) Simplify helper from Three.js seems a bit buggy: Small models tend to loose vertices, large models tend to simplify slowly and freeze the page
