This looks like a good timeline of the allegations. There was a lot of jumping to conclusions and people got hurt bad from them.

Show got shut down by producers who were not present to the incident.
Daily Mail fuels the fire with an unsubstantiated report of sexual assault.
Corrine, who had not yet finished her investigation and still trying to make sense of what happened, releases her first statement saying she was a victim. She cited that production shut down so surely something bad must have happened that night, right?
Basically, Corrine and everyone who thought something bad happened, jumped to conclusions based on producers who jumped to conclusions.
