## Troubleshooting
If you're experiencing issues with this mod, try checking this FAQ before opening an issue.
### I get an error saying that worldedit isn't installed
WorldEditAdditions requires that the `worldedit` mod is installed as a dependency. Install it and then try launching Minetest (or the `minetest-server` ) again.
### I get an error saying that `worldedit.register_command()` is not a function
This is probably because your version of `worldedit` is too old. Try updating it. Specifically the `worldedit.register_command()` function was only added to `worldedit` in December 2019.
2020-07-17 18:20:48 +02:00
### I get a crash on startup saying `attempt to call field 'alias_command' (a nil value)`
Please update to v1.8+. There was a bug in earlier versions that caused a race condition that sometimes resulted in this crash.
