Sandbox Security Issues since 8 01 patch

I noticed the CF Server list wasn't really linked on the site anymore, so I'm posting this here. I ran the 8.01 patch to our CF 8 install (a fresh install and a hotfix 3 install) and we are suddenly getting odd sandbox security issues. First, CF is being denied access to the CustomTags/ directory unless I explicitly add it to the files/dir tab under the webroot sandbox. This was never the case pre 8.01 patch, and I see nothing in the patch notes referring to it. The second issue is permission denied read/write to our file server on file uploads. If I add the <<ALL FILES>> wildcard everything works great, but if I just add the file server share paths I continue to get permission denied. Anyone else see anything like this? I wonder why pre 8.01 patch I've never had to add the file servers to the sandbox for uploads to work right. scary stuff?

No one else is getting this? :o This is scaring me!
