Okay, now I get the idea, thanks for Your comments, I've already taken action and fixed the work.

a new game is required for the lights to work as intended, if you enable mid game the already dead slashys will have lights on

Hi. The problem is probably on Your side because I'm testing My mods on a clean game.You may have your own modified SlashyBase.dir external file. Which is located in the folder Directors/Slashy/SlashyBase.dir.If there is one, then simply delete it and the light should disappear after the Slashy death.Files from the root of the game have absolute priority over files in the "Packs" folder or files from the workshop.Either your other subscriptions are using this file and there is a software conflict.

the light stays on when they're dead
