I have actually seen that on multiple pages but though it was a one day joke or something but I honestly am not sure anymore.
Here is another page where it can be found: https://warframe.fandom.com/wiki/Ballistica_Prime
(l'll try to update you if I see anymore of this.)
Okay, try refreshing, should be gone now.
I am running into the same vandalism here: https://warframe.fandom.com/wiki/Category:Nightmare_Mode_Mods
Here is another: https://warframe.fandom.com/wiki/Arcane_Pistoleer
https://warframe.fandom.com/wiki/Coprun
That still needs fixing
Flaicher fixed that one, try now.
