Like the title says. I am not sure why this is happening, but is just doing that.
Here is the link the build it deleted: https://www.diablofans.com/builds/101059-gr100-fort-mage-build-using-rathmas-high-damage
It's a known bug. Thru multiple edits your build is accidentally flaged as SPAM.
Happended to lots of ppl in the past months. Contact a mod or search corresponding threads in this Forum (plenty of them).
I sent this to the higher ups in case they were not aware of it.
