OXM UK has reported that Clover has been delayed and its creator, Binary Tweed, has placed the blame squarely on a "flawed approvals process".
Binary Tweed explains exactly what the blog entails and describes how because of one minor bug with Microsoft's XNA framework, which was immediately corrected, a week has to elapse before the approval process can begin again.
Sorry but one bug doesn't make a buggy game. Every game has bugs. And Big publishers DO get free passes sometimes.
If it's only a minor bug and it's fixed they should start the certification process right away.
