Your person.gd file is missing a critical mod function, which means that the mod did not install correctly or the file was tampered with afterwards. Edit: this problem seems to be specific to you, as it installed fine for me.
Viewing post in Chastity Belt Mod v1.3e (for Strive v1.0d)
This is weird, because I had the problem i deleted everything, strive game, the mod and even the strive folder at appdata and redownloading everything, 3 times so far and it still just crashes.
This person.gd file, is it possible for you to upload it somewhere so i can download yours and throw it into my folder or does that not work
Indeed manual replacement is a possible fix, it would behave the same as manual code changes, but will be erased if you use the mod system to add or remove mods. You should be able to copy the contents of the file "...\Es-02-ChastityBelt\scripts\person.gd" directly into your version of the file and add it to the end of the file with a decent text editor (crude editor's like Window's Notepad do not handle newlines correctly). But the larger issue is that such problems tend to not appear alone, and you may find yourself fixing many files.
Just to be sure, the mod system does not report any problems with applying the mods? It should be fairly sensitive to most issues, though the bugfix mod improves that a bit. It should report a lot of unused files, but the new actions folder, ChastityEvents.gd, and ChastityBeltMod.gd can be ignored.
Yeah in the end it didnt fix it completely. i didnt crash at start anymore, but when initiating sex and putting on chastity belt, as soon as i leave the sex screen and back to mansion a box shows up(supposibly have text in it but its empty) and i cant do anything at that point but just exit game.
I have installed diffrent mods before without issue. this one just seems to not install correctly. im using a new downloaded game so nothing is altered and there are no other mods installed on it, so its strange and my computer is just a dum dum.
