oh, I see the issue! I saw the error, but not what could make it too long, so thought it must be something else. Just saw what made it too long! Thanks!

It quite literally reports the issue in the exception itself:
> Path is too long. Path: [Home_dir]\AppData\LocalLow\Ludeon Studios\RimWorld by Ludeon Studios\Config\PublisherPlus\Temp\CHTechIndustries-Rimworld-Core\About\Mod Lists\CHTechIndustries\1.5\Rimworld Extended Properly\Only Soft Requirments\Endling- Last of Their Kind

This is a windows file system constraint, there is not much I can do about it without changing the inner workings of PublisherPlus to move away from creating temp files in the appdata folder.

okay, this mod is causing some errors. I made a discussion for, well, discussing (go figure) the issues over Here

it involves it not working one one mod, and working on another...

Yeah it does. Maybe in the future I’ll try to get in contact with the original author of this mod, and expand on it. Or make my own mod with the same functionality, but new code

@CTH2004 Sounds great. Ton of modders in the forums, for the right price could make that happen. We'd all enjoy!

@CTH2004
Those do sound like genuinely good feature ideas, but I have issues with touching a code base made by someone else. As it is right now I merely took up the torch to make the mod functional for 1.5, I do not intend to add features to it. I have way too much other stuff on my plate to work on extending PublisherPlus :(

I love this mod. Quick question though, would you be adverse to adding new features, or is it possible you will? If you are considering that, here's some thoughts:

1. add you name as well to the About File. after all, you've done some of the work too!
2. A way to use "wildcards" (typicaly an asterisk is used iirc). That way, I can block specific things from a group of folders. For instance, "about/modlists/ "folder" /.lnk" (bolded is wildcard) will prevent the uploading of .lnk files, but no other files, from within any folder inside "modlists". Could also be used to prevent you uploading text documents you put in as just little notes to yourself, like "remember to change name of such and such"
3. a way to prevent the uploading of specific file types. Doing this would make you never upload, say, a .markdown file to steam!

The best.

didn't know this existed nor that I needed it but I do now.
