Ninja Going Past Portal Bug

[astronomos8]

I noticed today that for some unknown reason all my ninja are going out PAST the portal, with the exception of 2 or 3 who insist on hiding in the beggar camp despite it being well withing our walls (which also annoys me, but it's only 2 or 3 of them). This seems to have rendered my ninja completely useless as the Greed wave spawns behind them. There is plenty of forest between my wall and the portal, but the ninja just run right past all of it.

I don't know what caused this, but I can try to speculate: Thinking about it, this only seemed to happen after (or soon after) I hired (or rehired) a ton of ninja during a Blood Moon. The ninja hiding in the camp behind our walls, however, happens whenever I've already hired ninja and then expand past the camp, so it seems like ninja stick to one spot permanently until that tree gets cut. It feels unlikely, but maybe I hired so many ninja that they ran out of trees in front of the portal, but that would only work if the trees occupied by ninjas who were defeated weren't then marked as open. Or maybe it's just something wrong with ninja AI.

Curious bug, doesn't surprise me.

I can say if you expand your walls past forest where the ninjas are hiding, they keep hiding there. That's been a bug for a long time, and I think they haven't fixed it because that one can be fixed by re-loading the game.

That does seem likely that the game just kept assigning ninja to hide behind the trees even though there was a portal there... I guess I've never tried hiring enough ninja that the stand of trees in front of the portal gets filled up.
