this is actually a duplicate of #164, or perhaps that is a duplicate of this. Either way, they are caused by the same thing, a null pointer exception in DDBoat$Type.getItem()

I can’t even place an echo boat in the first place.

That doesn't mean the issues are unrelated, and they are both caused by the same thing, your crash report just proves that.

This is a couple of lines from @wilsontulus's crash report:
Caused by: java.lang.NullPointerException: Cannot invoke "java.util.function.Supplier.get()" because "this.item" is null at com.kyanite.deeperdarker.registry.entities.custom.DDBoat$Type.getItem(DDBoat.java:113) ~[deeperdarker-fabric-1.1.6-fabric.jar:?]
and here is the same thing in yours, @NolanHewitt:
java.lang.NullPointerException: Cannot invoke "java.util.function.Supplier.get()" because "this.item" is null at com.kyanite.deeperdarker.registry.entities.custom.DDBoat$Type.getItem(DDBoat.java:113)

even if the situation that causes the crash are different, the cause of the crash is the same thing.
