Howdy, I'm trying to set up a dumb little modpack for me to screw around with using the technic launcher, mostly so I can still use client-side mods on my main client without having to switch the mod folders constantly. Anyways, as the title suggests, it's opening up in vanilla. I understand this is a relatively common issue, and have spent the last 2 or more hours looking at other members' help requests to little avail. As far as I can tell, everything has been done correctly.
The modpack is unceremoniously called Dat Survivor Boi, since Survivor was taken and I didn't feel like making something serious, as this was supposed to be a relatively private thing at first. Any help would be appreciated. I suspect it might have something to do with "coremods", but I haven't really screwed around with mods later than 1.7.10 before, so I am very unfamiliar with it. It's never been an issue in my past, and I'm doubtful it is now, but that's the only thing I can tell could be wrong.
Thank you for reading.
