All I did is bumped mixin extras. Memory Leak Fix probably needs to do the same and stop messing with mixin plugins.

Confirming CullLessLeaves 1.3.0 crashes with Sodium 0.5.2 and Memory Leak Fix 1.1.1. Solved by removing Memory Leak Fix (not ideal).

As CullLessLeaves is inspired from / based on CullLeaves, it's worth pointing out there was a similar issue with mod CullLeaves 3.1.0 not being compatible with sodium 0.5.2; this was resolved somehow in their 3.2.0 release.
I do not know if there was also an incompatibility with Memory Leak Fix. Just a thought, maybe it's worth checking how CullLeaves solved their incompatibility issue. PS: I do not have the knowledge to do this myself, sorry.

I closed this report because the issue is caused by Memory Leak Fix and not by Cull Less Leaves.

The crash is not caused by Sodium but by Memory Leak Fix.

Thanks for tracking down the incompatibility, I'm experiencing the same one, don't recall this occuring on the previous version of CullLessLeaves

It happends only with the latest version. (1.3.0)
