Addon misbehaved in the middle of a grouped instance and blocked interacting with party frame

[comiluv]

I was playing preservation evoker and in the middle of a Ruby Life Pools, below error message happened and I couldn't click or mouseover-cast on party frame anymore.

1x [ADDON_ACTION_BLOCKED] 애드온 'SortGroup'|1이;가; 보호된 함수 'CompactPartyFrameMember1:Show()' 호출을 시도했습니다.
