I was looking on the forum and clicked a link a mod had posted. Unfortunately the URL was not formatted properly. When clicking the link you were taken to:

https://asgardia.space/en/forum/forum/general-discussion-14/topic/we-will-need-many-embassies-on-earth-398/https%3A%2F%2Fasgardia.space%2Fen%2Fforum%2Fforum%2Fministry-of-foreign-affairs-67%2F

Which is a concatenation of the current topic's URL along with the destination's URL with all special characters stripped and replaced with their encoded representation.
