happened at the same time as "top squad yours" and "top squad theirs" came into the thing. no clue why i'd need to see only my top squad in those areas, but...shrug.
Off topic but same kind of thing. When you finish an outbreak and try to sell a weapon with no upkeep, it takes you to another city.
Thanks TonyDu for reporting this. Some backend cleanup of the social feed was released today along with the addition of the Top Squad groups, in the process the All group was broken. This is now fixed.
