This is a 4yo plugin so I don't expect fixes, but someone please make a continuation for C2/C3 as this functionality is just sweet.
The bug I found with current/latest plugin on C2 is that Transition to Camera never reaches the final camera and it doesn't set it as active. MagiCam.GetActiveCamera (weird PascalCase aside) is returning "transCam" for all durations bigger than 0.1s and just never gets to be the final camera, nor behave like the final camera. Bear in mind that they may have different lag values.
