[OpenSim 4.2] Analysis tool crashes if includes MFD #17
Description
As reported via email by user John Davis:
In OpenSim 4.2, attempting to run an Analysis that includes MuscleForceDirection will immediately result in a crash if the local_ref_system parameter is set to false. The plugin runs fine if local_ref_system is true, and it runs fine either way in OpenSim 4.1.
This is easily reproducible in the demo files distributed with the plugin. This crash occurs both when using the GUI and when calling the tool via the OpenSim API.
I scoured the 4.2 changelogs to see if I could pinpoint anything that would cause this change, but I didn't see anything obvious. When I check the opensim.log file, there are no error messages but the crash seems to occur before the coordinates file is read, because the log ends before the '[info] Loading coordinates from file...' and '[info] Storage: read data...' messages appears as they would in a successful run of the tool.
