Field destruction is displayed like a field creation of +0 MUs in the brief

In the activities zone of the scanner, field creation and destruction are reported with the same icon with a blue or green theme.
In the activities zone, with the scanner in English, field creation displays the MUs captured and field destruction displays nothing about MUs.
(I'm saying "with the scanner in English", because in French, the MUs from the field creation are missing in the activities.)
In the brief zone, field destruction is reported like a creation (because of the same icon) but with a "+0 MU" if it's not cropped out because of the portal name's length.
There should be some coherence, removing the MUs on destruction in the brief, or displaying the correct negative value in the activities panel and in the brief.
Different icons for field creation and destruction like for the links would be a plus.
