Hey Kulyok!
Thank you for creating and sharing this mod! Personality is exactly what was missing from the game. I've played IWD several times but I think I've had by far the most enjoyable playthrough, tagging along your merry group of adventurers (Teri is my favourite, she won me over almost immediately!)
I think, however, I might have come across a bug. I'm playing a female, half-elf bard yet the romantic options that got unlocked for me was Teri and Nella.
Holvir and Korin only spawned their friendly dialogue paths, with no flirty options.
Initially I didn't think anything of it, however I have now progressed to Chapter 5 with no change. Going through the Read Me again, I noticed that Teri and Nella are only available to male players while Korin and Holvir to females. I'm pretty sure the game recognises my character as "female", cue certain hilarious dialogue options, where you can correct the NPCs and proclaim you are -in fact- a woman.
I scoured this section of the forum but didn't see anyone having a similar problem. Something I've missed?
I'm running the original IWD:HoW, patched and have ToTL installed as well. Game version is 1.42.
