We'll likely need to add in an additional check for that event @ EventManagerRTG.java#L189 where we also...

1. return when (WorldChunkManager instanceof WorldChunkManagerRTG) is false, or
2. return if the dimension the event occurs in is not dim-0.

The former is the best choice for the future, maybe not with RTG-1.7.10, but with RTG-1.9.4 and beyond, as it won't be dimensionally restrictive.
