Im running a purge and some of the NPCs have fallen through the foundations and I cannot get to them thus unable to complete wave. Purge is now stuck until it times out?
Just wait. Eventually, another wave should start.
One does not have to kill all attackers in a wave; if some get stuck, that doesn’t stop the next wave from spawning. In fact, it makes things easier, as the next wave should be a bit smaller.
The purge only “breaks” if you manage to somehow get ALL attackers of a wave stuck or lost. That shouldn’t happen in any less than truly exceptional circumstances.
If you’re using modded foundations: In my experience, some mod sets seem a bit more prone to have NPCs fall through them. I replaced mine with Funcom foundations.
Conan Exiles… the game where the ground, isn’t the ground.
