You can report bugs in this thread or in the issue tracker[gitlab.com].

All bug reports must provide a HugsLibs log. To obtain one, follow these steps:

1) Subscribe to Log Publisher from HugsLib in the Steam Workshop.
2) Inside of the game and after experiencing the issue, press Ctrl + F12. This will launch the log publisher.
3) Click on the "Upload" button.
4) Press on the "Copy" button to obtain the link to the log.
5) Paste the log link in your bug report.

If you do not have HugsLib, you can also get a RimWorld log. You can check how to obtain it in section 6 of this link: https://ludeon.com/forums/index.php?topic=513.0

You can upload this RimWorld log to pastebin or similar services.
