We came across a strange bug during a show this afternoon that the dev team might be interested in. The setup was a PC FOH with a command wing, a laptop also FOH with a viz key and a third laptop backstage (with priority 'Never') logged in as a different user for the DSM to be able to see the cues. Towards the end of the show the DSM notified us that the numbers on the cues were different to what he had in his script. The first picture is from FOH where the numbers are correct. Going backstage (second picture) the cue names are correct but the corresponding number are not. Leaving the session and rejoining didn't help. Restarting the DSMs laptop didn't help. In the short gap between shows we reinstalled MA3 on the DSMs laptop (didn't seem to help) and restarted the FOH main and backup PCs. The thing that seemed to help (although might be coincidence) was we disconnected from the network, deleted all the saved show files and backups on the DSMs laptop and then rejoined the session. At this point the cues were correct.
Having fixed the issue I now don't have a broken show file to share but hopefully the heads up helps others spot the issue in the future.
