Eh what other kinds of mods do you use? And can you send a full log.

Here you are: https://paste.ee/p/lvsdK

I guess this is a race condition happening on world load. It doesn't crash the culling or anything, but I will fix it in the next release to prevent confusion.

In fact it occurred during the game as I was rushing away from a skeleton, looking around quickly to a better position and counterattack.
I also found this exception triggering rather weird since you were explicitly catching it. Perhaps it came as I finally killed the monster, and therefore invalidate the reference. I don't know.

[04:28:53] [CullThread/INFO]: [STDERR]: java.lang.NullPointerException: Cannot invoke "dev.tr7zw.entityculling.access.Cullable.isForcedVisible()" because "cullable" is null
[04:28:53] [CullThread/INFO]: [STDERR]: 	at dev.tr7zw.entityculling.CullTask.run(CullTask.java:103)
[04:28:53] [CullThread/INFO]: [STDERR]: 	at java.base/java.lang.Thread.run(Thread.java:831)

I'm also getting it from time to time without a crash, but shows in the logs.
