Hello, I've came into a weird bug that makes all easynpc's glow in the dark. They dont emit light but it looks like they have a weird texture layer like _emissive. Is it supposed to work like that? They look fine with normal light levels.

Thanks for the report. This is by design all NPCs have a default light level of 7 to make sure that they a clearly visible.
However I will implement a adjustable setting, which allows to adjust the light level of the NPCs.

With the next update there is an option to set the light level of the NPC.
A setting of 0 will use the surrounding light level instead.
