WTF? Uninstall deletes modules you've downloaded?

Uninstalled and reinstalled to fix the toolset crash. And now the toolset will launch with the 1.22 patch. But uninstalling deleted all the modules I'd downloaded or built! WTF?! That's at least 100 hours of work down the drain unless I can recover it via an undelete utility. Seriously, WTF Obsidian? How about asking if I wanted to delete modules?
