More than 1.2 million junk messages appeared in the server logs.

Nav mesh spam is not a new thing. It has been so common at times even before our library started, that there are plugins to get rid of the errors.

I need more information to be of any help here though. Which boss is throwing the error, what you've found and tried, any details that give me something to work with.

Narrow down which boss is throwing the error and look at what their spawn point(s) is/are and we can go from there.
