Isra_NPC VS Isra_NPC_BG2

Isra: Isra is a young paladin devoted to Sune. As a worshiper of the goddess of beauty, she’s no less committed to justice and goodness, but she’s not quite so… paladin. She puts me in mind of a somewhat less serious Cassandra from Dragon Age: Inquisition: her faith and morality are important to her, but she’s perhaps less severe. Some flirting in BG1, no romance till the sequel (see below).

Wlw romances: Isra (and her sequel link) - she's a paladin of the goddess of love and beauty. Nice if you like knightly types who don't take themselves too seriously, and I like the pacing as well - a little flirting in the first game, and an opportunity to seriously pursue one another in the sequel. Probably my favorite wlw character I've found. Sirene (and her sequel link) - more on the angst-ish side. She's a paladin as well, but she has demonic heritage. Again, nice pacing, good if you enjoy a slow burn kind of romance. Sarah - Sarah is a sweetheart, honestly. A bit shy but well-meaning, and though she's not devoid of angst or sorrow she's a refreshingly normal character.

A couple mod characters I like are Isra (cavalier paladin, romanceable by good PCs with 13+ charisma and high reputation) and Sirene (custom Martyr paladin kit, tiefling, romanceable by PCs with 12+ charisma). I'm singling them out because I feel like they'd be good adds to your party, stat and RP-wise; I also made a list featuring additional mod NPCs that I think are worth playing.

Isra: see above for full description.

I'm getting the impression that you like romance mods, so you might want to check out Isra and Evandra (https://www.gibberlings3.net/mods/npcs/evandra/). Both are, from what I've seen so far, well-coded and well-written mods. Though after the problems you've run into, I totally understand if you'd rather stick with the mods you've got!
