Clearing BuzzNav data--how universal is this solution?

Note: This is for Omega Ruby. I have not tested this with Alpha Sapphire. This is also on a US game, running on Gateway.

I regretted clicking the "mailbox" button in BuzzNav, as I got tired of hearing about things other people I don't know did. If it only gave me information about friends, I'd like it more, but just random people? I'd rather just see my own "news" then. So I looked through my save file for the BuzzNav data. Using HxD, I filled the region from 0x30800 to 0x30820, inclusive, with 00 bytes, and that did the trick. But I've only tried it once. It may be possible to have more BuzzNav data loaded (there were a bunch of zero bytes after that, which looked like it might be room for more, but I also saw a couple 01's and 02's mixed in there) in which case a larger region would be needed, or the addresses might even vary. This might even have some unpleasant side effects, which I may or may not discover when I next play, which is one of the reasons I kept an old save.

Can some other people try zeroing out this region in their save file to see if it works for you? Don't forget to load it in PKHeX and save it again to fix the checksum, or it will say your save file is corrupt.
