Hi Again,
I have had the free time again to deal with this issue and it goes like
this:
I uninstalled everything -game included- and reinstalled the mods
again and to my surprise the missing icon is there which means I must
have done something wrong.

Thing is: now it CTD's when travelling on map mode with time compression on;

Oh and another thing: if someone is willing to help pls tell me if
the order of the activated mods have been done properly and, most
importantly, if I have to install new mods the place I should place
them i.e. Mod A should be placed before B and after C and so on.
Thanks in advance.
