Crash caused by failure during APPLY (Found 0 candidate variables but exactly 1 is required)

[Luningor]

Here's the log.
I'm using Megane and WTHIT, along with Sinytra (which might be the culprit, although it worked before alongside it(? so I don't really know anymore). Sorry because it's a heavily modded instance and lot's of things might be, included that I'm a moron (in some way, shape or form). I hope this isn't the case, and that this is useful to you as well.
