This is a fork of https://github.com/Yurihaia/mcfunction. I have not created the base of this package, all the credits for that goes to Yurihaia, but I know how to edit the package to support the newest commands and items and I will also add quality of life changes. My goal is to keep the package up to date with the latest snapshots.
This behavior is not a bug. It is a result of atom's token limit. You can increase the token limit with this pack.
But keep in mind increasing the token limit can impact performance.
That's because in 1.17 the /replaceitem command was replaced with the /item command. But you can change the version to 1.16 in the package settings in order to use the /replaceitem command again.
Good catch. Let us know what about this package looks wrong to you, and we'll investigate right away.
