Fix | The latest update added support for end gateways to be used in combinations, however, this material does not exist in 1.7 nor 1.8. This resulted in an error being thrown when trying to use the elevators on said versions. This has been fixed.
Fix | Particles on 1.7 and 1.8 was also an issue. Due to the implementation of 1.13 support for particles using the 1.12.2 API this caused an error to be thrown. This has also been fixed.
