Just going to link this here Beyond-Reality/BeyondRealityModPack#103

Do not really know the solution to this issue looking for advice :)
Edit just gonna run some null checks. Ill leave it up in just for a heads up

See what's causing the NPE on this line: https://github.com/Beyond-Reality/BeyondRealityCore/blob/master/src/main/java/com/mcbeyondreality/beyondrealitycore/event/RightClickEvent.java#L62

Then just use an if statement.
