Omen of Putrefaction on Waystones

When I desecrated my waystone while also using the omen of putrefaction I did get 6 desecrated mods and it corrupted the waystone, but all of the desecrated mods were just normal map mods. I wasn't sure if this was intended or a bug, although I guess it may be too much loot if you have 3 abyss prefixes on a waystone.

Ran into the same issue, replying to bump this
