Again is it really an issue? From this text it doesn't seems so. But anyway, it's your post, I won't mark it as resolved (but I can't say someone else won't either).
Once a kata is solved more than 500 times in a language the tests are locked in that language. It's been discussed if this can be changed in the future but right now, that's how it is.
It seems to me this should be a suggestion, not an issue. See the kata creation date, it's from 2013, so old katas are probably overrated.
Well, a function with starting with "get" is not common in C# but as you wish I'll change it :)
:) This is all done. Thank you very much!
