Firstly, you should be able to view past edits via the page history. You are able to see previous revisions of a page at any given time, along with the differences between any two selected revisions. You should also be able to see which user edited which revision. If you need help on how to view this, I'm happy to help. :)
Secondly, the change was likely made in the first place since her species is an Alpaca - who are known as the Alpake within their native clan. While it's a fine line since the terms are synonymous within the world of Fœnum, for both clarities sake and to keep consistent with the other characters, Alpaca should be used with her species name. The developers themselves refer to Paprika as an alpaca officially, and if we were to use Alpake instead then that would mean the sheep would have to become Sheeple for example.
Again, I'm sorry if these edits frustrate you. Please let me know if I misunderstood anything you asked, or if you need any help regarding stuff involving the Wiki. :)
You know, it was actually only brought to my attention about a week ago that there are actually 2 TFH wikis. I have been taking a really good look at the other one (the one you just linked) and I admire your dedication - you appear to be the only active user on it currently. Looking at that wiki's list of admins (http://themsfightinherds.wikia.com/wiki/Special:ListUsers/sysop), it would seem there is only 1 - and that person's last edit was back in 2015.
I'll be honest - as an admin on this wiki, I would be genuinely interested in 'Merging' (http://community.wikia.com/wiki/Help:Merging_communities) the two wikis together. What are your thoughts? I'd appreciate the co-operation.
Now of course, as a non-admin on that wiki, you technically have no right to help dictate those sorts of decisions. Regardless of whether or not you would agree with my proposal of merging however, at the very least you clearly deserve an administrative right on that wiki. I would be happy to do my best to reach out to Wikia staff in order to grant you that proposal.
So I guess the TL;DR is this: Would you like me to attempt to grant you an admin role on your wiki? And if so, would you also be interested in merging both this wiki and your wiki together?
Thank you for reading this, and I look forward to hearing your thoughts!
Merging both of them would be a great idea, espicially since the game is about to be "Released" soon. And we're going to need to add the 7th character after all. So yeah, if you could help out, that'd be awesome!
