EDIT: I re-installed K1R. It seems to have fixed the issue. Cutscene plays as normal. Not sure what happened during installation, but oh well.
1) When approaching the Republic Soldier near the escape pods (just near that one Black Vulkar who you can kill or tell to get lost) in the Undercity on Taris, a cutscene plays. (Honestly I'm unsure if this is because of K1R, but because I can't find the issue anywhere else on the internet, I'm guessing it's due to the fact that I've modded the game.) After some lines of dialogue, he runs away from my party (still in a cutscene) and fights a rakghoul. However, he and the rakghoul just stay still. Nothing happens. I've tried pressing all keys, but nothing happens. I'm forever stuck in that cutscene and I can't access the escape pod.
2) Yes, I installed K1R 1.2 from Nexus Mods.
3) I have the Steam version.
4) N/A
5) It was a fresh installation. It was the first mod I ever installed to KotOR.
6) I followed a mod build from this link: https://www.reddit.com/r/kotor/comments/4yo3fd/kotor_1_and_2_mod_builds_guaranteed_compatibility/d6p71wn/?st=j4exgo62&sh=32c88e3c. It lists and has links to all the mods I have installed.
7) As stated in item 1.
8) No. As I have installed a ton of other mods, and given how adamant the readme was that I installed the mod first, I am hesitant to do so.
9) No.
10) No.
11) Windows 10.
12) N/A
