I recorgnized that some flags are not named correctly and show up as a broken image in the Security Panel where you can see the possible attackers flag.
So i just got a broken image instead of the flag.
eg:
Moldavia
in the path: /usr/local/cwpsrv/htdocs/admin/design/img/16/ there is a moldova.png
but expected is this filename: Moldova,-Republic-of.png
So i copied moldova.png and inserted the copy named as: Moldova,-Republic-of.png
i also recorgnized this with russia.
So instead of the country.png here the tooltip name was taken because this is exactly what pops up when you hover the flag.
I fixed this on my own the way i explained above, but i know on the next update this is possible undone.
So maybe this could be fixed in some future updates, it is not a big problem.
