Thank you for your reply.
Upon reading it i immediately logged in, put on my disguise and started looking.
Searched all around the fogfens first as per your description, but unfortunately Cid wasn't there.
Then i decided to just do a sweep of all quest places, found out i can't get into Cid's workshop anymore (though that might be normal), went to the place where you have to defend the armor and later do the jumping test with it.
Also did another round of looking through all of the castrum centri area and the area in front of it, but no luck.
So thanks again for taking the time to reply, but unfortunately i'm still stuck.
