My log is spammed 20/100 times/second with these errors.

I was pointed here as this mob is the first reference of any issues...

FML people said this is for sure caused by this mod. My server log is unusable as I am being spammed by this!

Won't help, I will need to ask other modders if it's acceptable to have null in the event, because if not then I will report it to Vswe.

I assume one of vswe's mods is calling the event with a null player instead of a fake player, which... I don't think should be valid in a "PlayerEvent". Not sure if other mods with autocrafting mechanics do that, I'll have to ask around a bit.

Please, I'll give you any access, even to a dev server if needed! This has been causing me a world of headaches :)

Is there a certain something on my server I should be looking to remove to avoid this error?

Will be "fixed" (read: swept under a rug) on HEE side in the next update. Might be worth telling Vswe to not use a null player in the event, but I think he knows that because the lag and log spam is caused by him telling it to do so, in case another mod doesn't check for null player (and why should it, this is the first time ever I've seen a null passed in that event).
