Vaal breach in Keepers league

Hey.

Seems like it is possible to obtain vaal breach in 3.27, Keepers league even though the patch notes said it won't.


Looking at poe.ninja, there seems to be quite a few people running it https://poe.ninja/poe1/builds/keepers?allskills=Vaal+Breach

Doesn't be a poe.ninja bug, as the gem also appears when looking at characters through official pathofexile profile.
