Hey, just found this thread. I've been playing the Aielund module off and on for years now. I've played through it completely at least 5 times, and am about to do it again with my first druid. Great to see there is still activity and interest! I've noticed bugs and typos as well, though many are foggy in recollection.
SPOILER ALERT
1. I did encounter that bug in the final battle of Act III at Fort Highmarch, where you are stalling until Terinus can teleport in and deactivate the Ironlord's shield. He teleports in, and says to attack, but he doesn't actually deactivate the shield. After having it happen on a completely separate play through, I think I deduced (through reloads) that it was because I was hanging out on the ramparts, far from the actual Ironlord's carnage. Maybe I was out of proximity for Terinus to detect me and trigger the sequence?
2. I've got so many hakpaks, custom erfs, and such in my NWN directory, I don't even remember if EMS is one of them and how to tell. I see an ems.hak in the hak folder. Is that all there is?
3. To the poster who seems to regret the disabling of Dev Crit; I thought like you, too, and decided to re-enable it in the game myself to experience it (the hak file has the STR prereq set to 99, so just change that). Mistake! It makes the last modules a breeze, especially
4. I would also love to be able to get a character to lvl40 without having to play solo (no henchmen), so a longer module at the end would be fantastic. Even now, you get to level 37 or so, and just as you're flexing your muscle, BOOM, game over.
5. Please don't remove mounts. Why do that? If they cause problems (and they do!), a person can choose to just {gasp} not use them. That is the simplest solution - allow player to decide if they're too buggy to use or not.
6. I have the Aielund Walkthrough doc on my computer. Send me a note and I can email it to you. It's not complete (ends like first part of Act IV), but it's still nice. It's also a bit out-dated, as some things it lists have since been changed or removed in the module, but it's functional.
7. I also experienced the bug in Fairloch where you
8. The bug at the end of Act I, where you come out of the caves with the princess, but the patrol captain doesn't "see" the princess. That will happen if she's using stealth, I believe, but I think it also happened because of proximity - she wasn't close enough to the captain.
