;go2 Identical Room Error

[Kaight the Innocent]

When traveling in the graveyard, there is an identical room with exits leading NE and SE that causes ;go2 to stop working. Someone said it might be possible to correct this with a peer tag, but what file do I need to edit and what would the tag look like? Below is the error received in game:

--- error running mini-script: 7313 -> 7314
undefined method `include' for ["ne", "sw"]:Array
--- Lich: go2 has exited.
