Should I include my Crash Report, or was that included when I clicked 'Report to Mojang' in the Minecraft launcher?

I deleted the 1.7.2 version folder and restarted my computer. 1.7.2 redownloaded and now my worlds load fine. Should I leave this bug report up, or mark it as solved?

Incomplete without crash report (minecraft/crash-reports/crash-<DATE>-client.txt). Please attach it so that we can diagnose your issue.

If you cannot find your Minecraft folder or the crash report, please use the Mojang Support Center.
