Not using that mod again.
There is nothing wrong with the mod (at least I have not seen a game where to mod misbehaves). However, if you use other mods then the chance for mod conflict is present. If mod X skips an attack, then mod winning condition does not know that and might count that attack towards the win condition. There is no 'mod loader' in wz, so during a turn the mods might run in any order. (You don't know if mod X or mod Y will run first. So if both mods affect the same territory then the end result might not be what you anticipated. Mods are not aware of other mods actions in the same hook).
This applies to all mods, but is particularly noticeably with the win condition mod.
Basically, when a hosts is using multiple mods, they need to make sure that they won't conflict. This might not be easy to predict unless you are, well familiar with coding. As a quick guide, any mod that uses the same hook (ie. Server_AdvanceTurn_Order has a solid potential for conflict) all hooks are here : https://www.warzone.com/wiki/Mod_Hooks
