Defect in “vote too old to be changed” check
I upvoted an answer, then cancelled it. Then later on after it was augmented/improved I tried to upvote again and was told I could not.
This is a defect I think.
There are lots of similar questions here on Meta, but there are too many for me to determine if ths is a dupe - because this is a special case and it is unclear to me if it is desired behavior or not.
IMO this is brain dead.
