[0.99.20]"-An AI fix for certain gate/wall configurations" screwed up my base

[Gabthelazy]

After a long 24 ingame days of travel across the land, I went back to my base to find out that units under a permajob, like "Operate Iron Mine" or "Staying close with x" can't cross my gate on their own, thanks to the update. I didn't have any problems prior to 0.99.20. Demolishing and rebuilding the gate doesn't fix it. Removing the inner makeshift walls doesn't do anything either.

Note, they might sometimes do it on their own, but for example, on my party 10 AIs following a character, only 2 managed to cross the gate.

It also seems to be affecting NPC AI. Had a squad of Holy Nation guys somehow get in my base, but where unable to leave even though the gate was open (their goal was "Aimless"). After destroying demolishing a random wall, they left through the open gate. I think the bug might also be affecting invaders as well, but I'll wait for next actual raid to make a statement on that.

Can you upload your save game for me?

I have same issue. My save game uploaded.

Imported and mod free save file. Building configuration has changed a bit, but bug always eventually happen. I recommend trying to pick up the sword outside. near the Ore Drill, or simply operating the Ore Drill through permajob for 15 to 30 minutes.
