as i dont play gnomoria, im not sure i understand this example… do units in that game auto-acquire resources (lumber, ores, etc.)?
from what we’ve seen so far, we’ll have a bit more control over what and where our units are collecting… but even if a unit was pathing towards a resource beyond your city’s defenses, the motivation system should hopefully kick in as the unit approaches a threat, and increase his priority to “live”, over his priority to collect the materials…
