I've made it to Korriban and everything is going fine until I enter the academy. I walk into the main room and Sion is just standing there but won't talk to me. Then I realize that a cutscene was supposed to play when you first enter that didn't play. So everything was set up for it to happen but for whatever reason it didn't trigger. Also the terminal that you need to access to open doors and such isn't responding either. I am using TSLRCM and M4-78 if that helps. I suspect one of them to be the culprit.
EDIT:
1) During the game, when did the problem begin to occur?
As mentioned above when I got to the Korriban Academy
2) Did you install the latest version of the mod? (1.8.4 and 1.2 respectively) We only provide assistance for the most current version of those mods.
Yep
3) What version of the game do you have? (Steam, GOG, 4CD, KotOR Collection?) What region is the game designed for if it's the 4 CD version?
Steam
4) Did you update your game as required by your game's region? (4-CD version ONLY)
N/A
5) Did you install this over the previous version(s), or did you perform a fresh installation as required by the TSLRCM's read-me file?
Fresh Install and first mod installed
6) What other mods have you installed? Please give an accurate list and provide links to each of these mods - even if they are found on this site. (We don't actually know them all!.)
A lot of my mods I got a long time ago from FileFront so links no longer exist. I'll put FF in place of a link to show if a mod came from FileFront.
