The MOST important thing needed with ALL bug reports is the Output Log.
Please read the instructions HERE before creating a new report.
By default, output log files are in:
Windows - %AppData%\7DaysToDie\logs
Linux - <game folder>/7DaysToDie_Data/
Mac - Next to the game's .app file
Copy the form at the bottom of the page and then hit the Add New Report button on the right.
Please report bugs to the Bug Pool, not in the General Support forum.
