Ummu log file error message

[Kendo]

New installation of Orbiter 2010PI (nothing else)
Installed Dans Arrow and UMMU mod only
Ran all UMmu scenarios and get this log file error on all scenarios.
As I am not the only one with these errors, I presume at this stage it,s the norm.

I've seen this more or less with any addon that change texture on the fly. (skinning)

[Kendo]

Wow Dan, that was quick thank you. So is the error is harmless?

Yep imho.

If we try to delete the ressource we get a CTD, if we don't we have this in log but no CTD, so
I assume it's a bug on Orbiter's part.

Thank you Dan for the explanation, very very helpful.
Out of curiosity, why do you need hires and quad res meshes and textures?
