@ -23,7 +23,7 @@ Current limitations:
- Only works with offline mode
- Only works with vanilla Minecraft clients, does not work with modded (e.g. Forge, FTB)
- Probably only works with Minecraft 1.17-1.17.1 (tested with 1.17.1)
- Probably only works with Minecraft 1.16.3-1.17.1 (tested with 1.17.1)
- This method will consume the client, following configured join methods won't be used.
At this time it is unknown if some of the above limitations will ever be lifted,
