Confirm the version
Open HDT Options > Tracker > Plugins and confirm it shows `LethalCue 0.2.21`. If not, download the current ZIP and overwrite both DLLs.
Test feedback
If the LethalCue panel does not appear, damage looks wrong, or a direct-damage card is not recognized, use this checklist. v0.2.21 records your own hand card IDs and costs in the diagnostic log so missing rules can be fixed quickly.
Open HDT Options > Tracker > Plugins and confirm it shows `LethalCue 0.2.21`. If not, download the current ZIP and overwrite both DLLs.
Take a screenshot showing your hand, enemy health and armor, your board, and the LethalCue panel. A panel-only screenshot is usually not enough.
Open `%APPDATA%\HearthstoneDeckTracker\Logs\lethalcue_debug.txt`. You can also run `collect-feedback-bundle.ps1` from the ZIP to package the log automatically.
Write whether you expected lethal or no lethal, the damage you counted manually, and what the plugin displayed.
