There are some outdated flags in the flagsets:
Lesotho flag (ls.png) is right in the flagset 1 but wrong in flagset 2.
Malawi recently changed its flag (mw.png) (http://en.wikipedia.org/wiki/Flag_of_Malawi), so the flag is outdated in the both flagsets.
Additionally, flag of Ethiopia (et.png) in the flagset 2 lacks ethiopian coat of arms in the center of the flag in contrast to the same flag in flagset 1.
Outdated flags [FIXED]
Re: Outdated flags
Sorry for the late reply (I somehow lost this post in my inbox) but I've fixed these three. The Malawi flag was fixed in this month's 4.1.10 update along with a few others and the other two issues with the second flag set have now been fixed for the 4.1.11 update to be released next month.
