Crafting-related errors after this week's wipe?

Hey! Since the Thursday wipe (Aug 6) some of my players have been getting kicked with "Invalid Packet: Client Ready" right after connecting, and my console is getting spammed nonstop with this:

NullReferenceException: Object reference not set to an instance of an object
  at (wrapper dynamic-method) MonoMod.Utils.DynamicMethodDefinition.ItemCrafter.FinishCrafting_Patch1(ItemCrafter,ItemCraftTask)
  at ItemCrafter.ServerUpdate (...)

It happens as long as someone has something in their crafting queue, and seems to get worse the longer the server runs. I'm on QualityCrafting v3.0.4. Not sure if it's related to the plugin or something on my end, but wanted to check if this rings a bell for you or if anyone else has reported it after this week's update?

Happy to send more of the log if that helps. Thanks!

this happened on my server too, but its not this plugin that caused it, anything that increases craft speed got affected and will give players an unpleasant hoofing from the server, unable to get back online until the server restarts.
