Bugfix PSCR Settings in Simulator Mode: The dive settings structure is not filled at the start of a simulated dive. As result changes in the PSCR parameters were used by the simulator unless the OSTC was restarted. To solve this problem the update of the dive settings have to be triggered after a parameter had been changed.
