Does anybody have an idea why I get this warning when I use any nimble task in my project? `Warning: Multiple dependencies require different special versions of 'buju': using #head, ignoring #head. This will become an error in future versions.` This is the relevant part of my `.nimble` file and the output of `nimble dump` and `nimble check`\: https://play.nim-lang.org/#pasty=FoeACuvG I need the `#head` of dependency "buju", because the latest tags of the project do not contain important fixes/changes in the project, which I need. https://github.com/haoyu234/buju AFAICS there are no dependencies on "buju" declared elsewhere.
