Minecraft 1.16.1 is out! With that update comes new assets for Mine-Imator, which are downloadable when you start it up. However, after trying three times to download and start Mine-Imator with the new 1.16.1 changes, the loading bar gets stuck on slab and will not proceed. I don't know why this happens - I can load up Mine-Imator with 1.15 features just fine - but something just goes wrong when it's trying to load up a 1.16 slab?
How to replicate my issue:
Step one - Open Mine-Imator
Step two - Accept the prompt to download new features
