I downvoted at the cost of 1 reputation, but it shows in the achievement bubble as +-1
, and it's green instead of red.
As people have noticed, positive net rep gains also contain the hyphen. The displayed number is the sum of positive and negative, but the +-
is always there, though possibly only if there was at least one negative value?
+-2
.+-
is certainly confusing and a bug. If you read the OP above, it displayed+-1
for a rep gain of-1
, and it displayed+-2
for a rep gain of+2
. So it's showing the+-
for both positive and negative net gains.+-x
means "positive or negative x reputation".
