-- I created the tags
-- I attached them to emails
-- I archived the emails using the built-in archive button
(my Archive folder was set up to sort by <tags> and <Grouped by sort> )
A couple of days later I go into my Archive folder to check on something
and all of the new customized tags are gone and the messages are grouped
by an "untagged messages" category.
The laptop in question ( running TB3 on Win7 ) had never been rebooted,
only put to sleep between work sessions.

if they are missing from the options list, you can reproduce this issue
in safe mode [1], and don't see this in the bug list [2], then please
file a bug report
if there is a separate issue related to archive, can you reproduce the
problem by manually moving a message to the same target archive folder?

Just check if they are still in preference.
Goto Tools > Options > Advanced > General > Config Editor.
Type
mailnews.tag
It will list all tags present in your installation.
Just as a temporarily workaround you can do following.
Create all missing tags again in TB.
Now, goto Tb profile folder and create (if doesn't exist) a file named
user.js.
Open it in your word editor.
Open prefs.js file in another editor.
Now copy preference corresponding to each new tags (mailnews.tags.<Tag
Name>.tag , mailnews.tags.<Tag Name>.color)
and paste the content in user.js file.
When done, save user.js file and restart Tb.
