v5 - works, doesnt taint? or only on uwow server?

I left some code made by Leatrix, which is not perfect, for combat vehicling.
followed this commit by Leatrix:
 https://github.com/leatrix/leatrix-plus/commit/4178b6fca263de759ab8ecd3a744129cd6abf584
I tested on Warmane, Whitemane, no taint. Taints only on UWOW server.
