Large PTR update but i see nothing on forums?

Why do i have a 50ish gb update on PTR but i see no info on the forums

PTR hasn’t been updated in 6 days. The last update notes are here.

thn why did i have a 53gb update ?

Ill play.

Why did you have 53gb update?

Couldn’t begin to tell you, but it hasn’t updated since the 17th. It must not have updated before.

well thats odd, thought maybe they added a bunch of stuff into the ptr before the holiday, guess not
