See how fast things get changed/fixed or edited when $$$ loss due to exploitable bugs or information players are not supposed to see.
I believe the community did not want that changed, it was nice seeing what the new Season Ops and its rewards are going to be. It may have been an error but nice seeing useful info and a headsup on what to expect.
But when it comes to what players do want changed or fixed... changes never occur...hmmm
PS if you check social media you can see the 3 new tanks and their commanders on some screenies and videos
