As a shortcut, A = stack inserter, B = filter stack inserter.
I had a wired inserter with the setting "enable if A > B". When I copied the assembler producing B and pasted onto the inserter, it generated this crash:
971.717 Error MainLoop.cpp:1173: Exception at tick 9186605: The mod Additional Paste Settings caused a non-recoverable error.
Please report this error to the mod author.
