* Fix handling FeatureSet related entities.
* Add 1.20.4 to build.yml
* Turns out jsut need to enable the feature set in the server.properties
* Remove the server.properties
Lets not enable feature sets since they could change alot of stuff on use.
The other fix in the PR still works as it makes it so that the entities don't show up as player type, just as unknow if we can't get them.
* Use the same way of getting the entity in all parts of the generator.
This should help deal with entities from features, since using the factory directly gets around the feature check.
* Would be helpful to call the function correctly...
