It may just be spam but in my papyrus log I get about 300k of this over and over again in one form or another but alwasy about the ENCQuill.

"Error: Property craftingStation on script xxxENCQuill attached to Item 4 in container (5C046694) cannot be bound because (0928396C) is not the right type"

Anything I should be concerned about?

I'd ask the mod author of whatever mod contains the script "xxxENCQuill". It would be best for them to investigate and fix the error.
