I made stable repro that can repeat two bugs.

My program randomly starts events in random positions.

First bug:
getEventByIndex returns FMOD_ERR_INVALID_PARAM.
Several events always fail. I’ve tried start breaking event first and getEventByIndex has failed.

Second bug:
For some events getEventByIndex returns FMOD_OK, but future calls for this event returns FMOD_ERR_INVALID_HANDLE.

I can send to you repro sources and fdp, but I can’t send to you all 10000 sounds. If you need anything – just tell.

Thanks.
