Every time that I try to add a ‘Event Track’ to TimeLine I receive this error:
EventNotFoundException: [FMOD] Event not found: {10c315b8-199a-4031-b482-cb35d0dc6789} (event:/CG/CG\_1000103\_zs)

Hi,
What version of FMOD are you using? Are the banks being refreshed correctly e.g. do you see the refresh prompt after building?
