## 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.

### 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.

### Why don't the [moretrees](https://content.minetest.net/packages/VanessaE/moretrees/) trees work with `//forest`?
As far as I can tell, the saplings provided by the [`moretrees` mod](https://content.minetest.net/packages/VanessaE/moretrees/) don't properly interact with bonemeal from the [bonemeal mod](https://content.minetest.net/packages/TenPlus1/bonemeal/), which WorldEditAdditions uses to grow trees. As far as I can tell WorldEditAdditions has everything in place needed to support them, but until applying bonemeal to `moretrees` saplings results in a tree rather than waiting for one to grow over time, WorldEditAdditions will always fail to place trees provided by the `moretrees` mod, unfortunately.
