Telltale games are always comes out with graphic issues and low frame rate but seriously I don't think the save issue is their fault. The problem you are talking about is happen only on X1 version. There are more games with the same problem on X1. I am not 100% sure this is the TT problem.
Here is the source
http://www.xboxachievements.com/new...e-of-Thrones-Hit-By-Save-Bug-on-Xbox-One.html
That source doesn't say anything about it being an XB1 problem instead of a Telltale problem. I'm not convinced - I think this falls squarely on the shoulders of Telltale, and they should be responsible for fixing this bug. But I don't think they are sufficiently motivated to do so, which is a real shame.
This is not a good video game company - they don't respect their customers.
edit: Last Uchiha, are you referring to comment#1 on the article? "Fuck me a broken and glitched game on the xbox one? surely not? wish my cock was as long as the list of broken games that get released" I've had minor problems with some games but nothing to suggest there's an XB1 epidemic. Unfortunately my cock is longer than the list of broken games I've encountered.
