Summary0008776: assetSystem.IO.IOException: An attempt was made to move the position before the beginning of the stream
DescriptionWhile a region (on DreamGrid with Hobbiton 3x3 OAR content) is starting up, on every occasion, I see this red error... it appears to be while the (Warp3D) map is generated. Reporting this in case its something that may have a fix. There are a lot of animated objects, NCs, etc in the region, and I am sure some of them will be active while the map is being generated.

Switching map modules it goes away?
Does it happen with master code as well?
Mesh decode can be really spotty, you can enable some additional information lines in code if you need more info on what it is failing on. That may help at least figuring out which object that is, though given the error it may not be aware at all.

sounds like a defective mesh asset

But what about the move of position message?

@Tampa ... thanks, I can try a map option other than Warp3D. But that's nit the point. I was noting the error in case its something that might indicate an underlying issue. Its a minor issue as I stated. It does not stop the content being used.

The Hobbiton OAR though is limited by its license to use on DreamGrids.. which currently uses OpenSim from about a week ago, so its almost fully up to date with 0.9.2.0 dev master.
