Error: An invalid object handle was used

I really doubt it is F$$anonymous$$OD. Could you pleas elaborate on what your game/software do? Does it utilize any third party plugin, networking or anything extraordinary?

Nothing extraordinary - its a game with not too many plugins. The only "heavy" plugin I am using is $$anonymous$$amcord. But the game only started reporting these errors when I built with Unity 4.2, prior to that I had no issues and never seen this error.

Why do you think its not F$$anonymous$$OD? On google, all pages that mention this error either talk about F$$anonymous$$OD or sound.

I guess I'll take it back what I said, apparently this appears to be rooted in F$$anonymous$$OD. I was just personally sure I have seen the same error somewhere else.

But I understand what you mean, with a quick google search, plenty of results comes up with the error message related to F$$anonymous$$OD.

Could you try build the project without any sound? Disable all AudioSources / Listeners and build it again, to see if the problem even arises from there?

Thanks. But no, building anything at this point is not practical, simply because I do not see this error on my device, but rather on remote, unknown devices. I did send an email to the nice guys at $$anonymous$$amcord, because this is the only suspect at this point.

I am also getting this error sent to me from a Windows 8 PC at the beginning of a new level of a game (intermittently, and only in a certain level).

The error only happens on this one device. I will try to get access to it and investigate.

An error occured that wasn't supposed to. Contact support.

(Currently using Unity 4.3.3f1) (I am not using $$anonymous$$amcord or too many other plugins either)
