Chunks with lot of redstone are removed when converting a world from 1.11 or older to 20w18a

java.lang.NullPointerException: null

Note: No stacktraces are logged, possibly because the wrong logging methods are called (last parameter is Object and not Throwable)? The class logging this is called yf in 20w18a (Mojang name: net.minecraft.server.level.ChunkMap).
