I wanted to propose upload as synonym of file-upload (I would personally like it to be the other way round, but given that the community has used the file-upload almost as twice as much, I'd imagine that this is a much more preferred name, but OK, that's not further related to the concrete question).
However, I got the following error:
Which is strange. The uploads is already a synonym of upload. I'd imagine that this problem is caused because propsed tag synonyms are not removed/cleared when the tag itself becomes in turn a synonym of the proposed synonym tag. It might as well be related to singulars/plurals.
Is this a bug?
