Notes: Before posting, reading the last red advice in the posting page, I looked for the .mdmp file... and I realized I had 20 of them. Is the first time I repport something here, I didn't know about that file, but none of them had the date of today so I didn't add them, I hope is okay.

Thank you very much for existing Klei haha I love you devs ♥
