My xbox 360 has frozen twice in different places in the world but both times right after clicking a on a newly discovered plasmid. These were two different plasmids in two different locations.

The first time through i hadn't saved so i had to start over when i found a new plasmidnear the telkenisis one and clicking a on it froze. And on the second time through the medical level when i clicked A on a plasmid i had already found and used the first time through this time it froze.

Is anyone else having this?

It's pretty fishy that it happens doing the exact same thing in difference places. Maybe it's a bad disk? Maybe the data stored to play the little movie detailing your new plasmid is stored on the same defective spot on the disk?
