is there a way to fix it? im not much for messing with files usually, especially modded ones so i have no clue what id have to do lol dont wanna mess anything up
Use 7zip or what have you to open the .pacc, find the data.hjson file and open it, that's where all the code bits are. Fixing things from there is fairly easy. Using the log file it'll tell you the error and more specifically where it is (something like line 50, column 40) and then using a data file you know works you can compare and contrast to fix the errors like missing brackets {} and the like.
Alternatively you could make a temp txt file, copy-paste the informational data (name, birthdate, etc), the features (at the bottom), and note the foreplays the character has. Then take a data file from a character you know works, copy-paste it in there and just replace the name and other stuff you grabbed. You could also make sure the orifice sizes/skills are correct as well, but changing them won't matter that much. You're just fixing issues with the code formatting.
Also make sure you're copy-pasting the entire file, 3 or 4 weren't working just because there's a } at the very bottom of the data file and they were missing it. Other common issue was {{ at the top of the file.
