"visual editor did more than i told it to: https://en.wikipedia.org/w/index.php?title=Cameroon&diff=611127082&oldid=610427158 " "hmm looks like ve actually removed a duplicate parameter when i made that edit" Seems this occurs when you edit a template in some way (e.g. adding a new parameter), if a named parameter has been set twice. Not sure if this is intended behaviour or not. Bug might be a dupe, might be in Parsoid instead of VE, or something else.
This is intended behaviour, yeah; we won't dirty-diff to fix broken wikitext when you edit something else, but VE will always fix up bad existing formatting when you change the item.
