In 1.31 and earlier, when a map associated with a replay could not be found the replay was still shown to the user with the in-game browser. Upon trying to watch the replay an error message was displayed indicating that the map could not be found.
This behavior has changed in 1.32. Replays whose associated maps cannot be found simply are not shown within the in-game browser. Only when the map is found do they then appear. As such, a user will not be able to determine that a map in a different or wrong location is the issue.
It should be noted that starting the replay via the command line in 1.32 does not exhibit this problem. The old error message is shown, indicating that the associated map cannot be found, and including its expected path.
