Fixes & Improvements Fixed Lua errors caused by SetAlphaFromBoolean and restricted API values Added safe handling around UnitIsUnit() using pcall Prevents crashes when Blizzard blocks target comparisons Behavior Targeted spell indicator now updates reliably on UNIT_TARGET Stable in combat with no error spam Falls back safely (hides indicator) if comparison fails Performance No extra allocations Early exit on unnecessary updates Efficient handling of group changes UI Keeps red square indicator above party/raid frames More consistent visibility during combat Notes Blizzard API restrictions may block some target checks System prioritizes stability over perfect accuracy

I have tested as dps in m+ and found no errors, and it seems to give the indication on incoming spell on party frame.
