The Walking Dead Episode Four: Around Every Corner, resulting in lost games and decisions. Telltale patched the bug last night on PS3, its Twitter reads.
Telltale previously told us that it was possible to avoid the glitch by "refraining from use of the third save slot in the game menu." That should all be fixed up nicely now, but like the 13th floor of a haunted hotel, maybe you want to avoid that third slot anyway.
We've contacted Telltale regarding potential glitches across other platforms.
