Google - does not like redirect to homepage

In the little section

"File Not Found" requests handling?
Select how 'File Not found' requests will be handled:


I had my vbseo set to redirect to homepage (after reading a post recommending it!) Google suddenly stopped visiting my site. For the best part of a week I left it to see what would happen .....nothing did!

I revisited the webtools section of google and it told me that it didn't like the fact 404 errors were coming up as successful. So having now removed this redirect google is now happily trawling my site again.

Has anyone else had this issue or noticed similar problems? It should be noted that it didn't seem to effect the yahoo spider.

I havent seen that option at all, but I agree I wouldnt redirect non existent pages to the homepage.
