Also, I tried to save Delena, scouted the camp, found her, gained her trust, planned her escape...and for some reason the next time I went there the game was hell-bent on making her the old chiefs whore...or Tarish will make her a sex slave. No other choice. Why can't I save here any more?
This game is really bugged, I don't even the option to buy stuff from Cla-Min, Alexia event do not proc at all. Ssheeehhh.
During your first visit to Tarish, unless you decline to work with her, the game is gonna assume the preparations you can make to rescue Delane are a part of your plan to help Tarish, and actually helping Delane escape will have to be a last minute decision Rowan makes to betray Tarish.
When visiting Delane in her cell, you will have two dialogue options, one will encourage her towards giving herself to Ulcro, the other will just get her to befriend and trust Rowan, if you picked the Ulcro option even a single time the game is gonna assume you're potentially interested in doing Ulcro's route so it will be referenced in the dialogue and narration.
The game is still a bit buggy and missing some mechanics, equipment is being reworked and until that's done Cla-Min's shop is closed. I do not know what Alexia event you are looking for, I can only tell you weekend events have conditions to them, but the game will randomly select any of the valid ones. Maybe the event you are looking for requires certain stats you are missing, or maybe it only happens after or before X weeks. Potentially, you got unlucky and an event that can only happen early in the game never procced in time, the devs try to get around this by making certain events be "high-priority" a few weeks before they can no longer proc, but if you have too many "high-priority" events queued up then it is possible it just gets missed and ends up being impossible to get in that playthrough, definitely a possible bug.
