In TDB they have only horde spawns for NPCs and some GOs, thats why when WG owner changes they work good. YTDB have all 2 spawns (1 - when horde owns WG; 2 - when ally owns WG; 3 - for some NPCs, when WG finished), thats why you should delete ally spawns to bring this patch work with YTDB. GL & HF.
