Enemy Troops don't Despawn

[Deantwo]

My capital city Rævehjerte is right now reporting the presents of an enemy Weltreich troop, but I have not been able to find one anywhere. And before that I was still unable to build a base because seemingly is an enemy Weltreich unit somewhere else on the world, Tail V.

EDIT: Found the enemy troop hiding in my carpenter, I shot him and my world in no longer under attack. Only took me ~4 days to find the troop...
