(1.21.11) Server crash because of FastScan

[0xSniffa]

Yo so we've been using the mod for a bit now and it's made Perimeter creation so much easier. Tho we encountered an issue where the server crashes since it apparently tried to get the waterlogged state of air. We're on 1.21.11. Here's the crash log:

java.lang.IllegalArgumentException: Cannot get property class_2746{name=waterlogged, clazz=class java.lang.Boolean, values=[true, false]} as it does not exist in Block{minecraft:air}

Addition: It happened when scanning for liquids (water, lava) in a bigger area.

Alr so I did some more testing and here's what I found out. When you add waterlogged = true to any scan it crashes the server. Doesn't mater if you do Block_XYZ AND waterlogged or if you just do waterlogged = true it always crashes the server. Hope this helps.
