Saving ttm issue

[huangyzzzzzz]

Hi,stepjam,I have an issue of saving the simulation ttm file, the prompt of task builder thrown error as following:
pyrep.errors.ObjectIsNotModelError: Object '%s' is not a model. Use 'set_model(True)' to convert.
QObject::~QObject: Timers cannot be stopped from another thread
QMutex: destroying locked mutex
can you give me some advice of solving it?
best, regards.
