[firenoo]

ae2 version?

[SrYthan]

this version
appliedenergistics2-rv3-beta-250-GTNH.jar

Inside the chest are some items that are pulled into the system from a farm, I tried to manually throw the items into the system and the same thing happened, I believe it is due to an auto crafting that I have

[firenoo]

Is the issue still happening?

[SrYthan]

I discovered what it was, when coding a pattern-encode and placing it in an interface and then removing it from that interface, somehow it got stuck in this interface that it still knew how to make the item encoded in the pattern, which caused the crash when the coded item entered the system, so to solve it I coded the pattern again to make the item in question, I placed the pattern within the same interface as it was and removed it and that solved the problem.

[SrYthan]

so I believe the problem is that the Me-interface was stuck, as if it still knew how to craft the pattern-encode item even if the pattern-encode was no longer inside the ME-Interface
