Map them onto the existing values, the exact mapping will depend on what
those events mean, force disable or out of regulation look like likely
candidates for example.  If there's anything that's just not covered
then perhaps a new event type is needed.

Please delete unneeded context from mails when replying.  Doing this
makes it much easier to find your reply in the message, helping ensure
it won't be missed by people scrolling through the irrelevant quoted
material.
