@kiwininja;
Thank you very much for the reply and the message, much appriciated

It also feels good to know that i am not the only one in the history of M&B who ever had such (or similar) problem with a companion

The thing is;
I am currently 100% natural in the game,
meaning that i am not a vassal of any king, and neither am i the king of my own nation in any way.. (all nations are neutral twords me)
So, besides your regular bandits and raiders etc.... I have no enemies. I was just thinking of creating my own kingdom BEFORE Matheld disappeared.
When she did, i kept on playing AS USUAL for about 3 in-game months (travelling, fighting, exploring,doing missions etc)
UNTIL i realized that something was/might be wrong.
Usually after 3 months; travellers tell me about the location of a by-gone companion if i ask em, but this time there was no mention of Matheld whatsoever STILL,,
so i kind of ''fast-forwarded'' the game about 2-3 more months, constantly travelling between large cities to find different travellers, to have a clue about her whereabouts, but she is still missing..
Its not the end of the world, but only because i love this game so much, this problem is irritating me, its really hard to explain
THANK YOU again for the answers that you have given me so far in any case

PS 615vs66? OMG heheh....
