Quite frequently when I throw evac flares, some of the evac evac squares don't work, even when the flare is on open ground with no walls/dividers of any kind, I often have 1-3 squares which are bugged.
It only happens with player placed evac zones, pregenerated evac zones work fine.
I suspect it's a parcel issue, but I'm not certain.
Bugged evac zones.
Re: Bugged evac zones.
Usually it's not walls, but overhanging things causing this. The tiles are blocked from above by something. If that isn't it, please post a screenshot (or much better, a saved game) of a zone that isn't working correctly.

I'll remember to next time, but I've had it right out in the open.
