Thanks for the heads up, @Trinityyi!

I cannot reproduce easily, but it seems that using ugly URLs (with trailing /) when linking should fix this. Netlify and Gatsby will redirect the ugly URL to the pretty one anyways, so that's pretty much an easy fix. Added to the current sprint, shouldn't be too hard to fix over the weekend.

Possible solution

Add a check for internal links not having a trailing /, account for URL parameters, add the trailing slash before sending the link to the Link component and it should be good to go. Doesn't break anything, requires a couple of extra tests.
