When I tested patchwork, everything worked fine except when I actually opened Minecraft with the mods installed. Minecraft would start, but then eventually crash. It said something along the lines of: "Patchwork could not load this mod correctly" or something like that, in the crash report. I don't know if this is a bug or if I did something wrong when setting it up. Also, I got that version of Patchwork from a YouTube video, and I think it was version 0.3. The mod I converted was the travelers backpack mod, which converted just fine, the problems only happened when I tried to open Minecraft with it, fabric API, and Patchwork API. when I was converting I didn't put anything in the data file before I ran patchwork, because the YouTube video didn't show to put anything in there. If I was supposed to put something in there, you can tell me.

`- Can I use it?
The short answer is: No.
The long answer:
Patchwork only runs a few mods (as of writing only a few mods )
Patchwork is not looking for testers, and we do not want people who are not writing code for Patchwork using the software.
As such, nobody is required to help you run Patcher or use Patchwork API with your favorite mods.
With that being said,
You can always open bug reports on our github pages
Everyone is encouraged to ask questions in the Development category about writing and using Patchwork's code, or asking about how Patchwork works.
This note isn't a restriction on giving help, but instead a warning that you shouldn't expect official support.`
TL;DR: Patchwork is not done yet, and very few (only 2 known) mods work on 1.16. Whoever made that video is likely lying.
