Quicklisp broke after (ql:update-dist "quicklisp")

[jnc-nj]

Error: FIND-SYSTEM-IN-DIST returned #<SYSTEM alexandria / #1=alexandria-20170227-git / quicklisp 2017-02-27> but I expected one of (#<SYSTEM alexandria-tests / #1# / quicklisp 2017-02-27>) While executing: #<STANDARD-METHOD QL-DIST:INSTALL (QL-DIST:RELEASE)>, in process Listener(4). Type cmd-. to abort, cmd-\ for a list of available restarts. Type :? for other options.

Alexandria couldn't be found thereafter. However, after restarting CCL everything appears to be working as normal.
