I’m not entirely sure if this is a bug or if I’m missing something obvious and crucial…
Anyway, I’m currently at the end of the mission “The Plan” for Jericho, where the objective is to defeat the gatekeepers, defeat the Yuggothian Receptacle and finally place a beacon.
The gatekeepers are down, the gate is open and the receptacle has been defeated from long range - but my soldiers can’t advance beyond the gate, as the territory beyond it is all X-ed out, and so the mission can’t be completed.
This is definitely a bug.
Have you use F12 ingame to make a bug report? If not, then do this, then the devs get your save with all informations at this point of you play through and can look on it.
