Blender should not loose vertices, edges or faces on import, at least not with Collada.

Thanks again for the patch.
It is now commit to master
Thanks for this report!
I fixed the set enumeration to start with "0" (like in blender 2.7) instead of "1"
Thanks for the patch! It looks ok to me.
- fix unreported: collada mesh importer: Remove duplicate calculation of Normals.

Fortunately the unexpected behavior is actually very expected but it needs to be documented better. The problem is that Collada does not support bone chains (connected bones) out of the box. The importer has 2 options for automatic recognition of bone chains, but this recognition fails sometimes. In your case the Skeleton was auto connected to the CenterMass bone and thus it changes the animation. The good news is that the fix is super easy. Also the Importer can be told to not auto connect to avoid the issue at all:

Thanks for the updated blendfiles.
I can not open the blend file:

There are many reasons for getting parsing errors with Collada. But really, this report system is for reporting errors related to Blender and not so much about importing issues into target engines. Unless a target engine complains about wrong Collada format, then we are back at work here. But then we also need to know what the complaints are exactly. And a demo blend file of course, as always :)

I am sorry, i overlooked that the textures are present in the zip file. I give it another look later. It may also well be the case that the issue has been resolved as i am steadily (and admittedly only very slowly) working on fixing the Collada exporter since about 4 years now. Also with Blender 2.8 everything changes :) The new Collada exporter is already in the 2.8 Beta but it has not yet been tested to the very details.

I fiddled a bit with your proposal...from those i like the second from the left best. However, if none of those alternatives work for you, then i'd go with your favorite (top/down arrows)
Thumbs up from me for the third one as well:)

While adding the fix, i found that the related definition files are available only since Collada 1.6.68 So this fix will only work for Collada 1.6.68 or newer.

This particular "DAE parsing issue" is caused by negative object scaling which the importers to SL and OpenSim seem to reject (see error logs in the Viewer). However negative Scales are actually not forbidden by the Collada specifications, so this is not an error in the Collada Exporter, but an error in the Model.
I could not find an easy way to get the library version number. So i asked in the opencollada project:
The support for action clips has already been prepared in the Blender Collada module since march 2018, but discarded because actually i was waiting for https://github.com/KhronosGroup/OpenCOLLADA/issues/565

Please follow our submission template and guidelines and make a complete, valid bug report,
What happens when you uncheck the option ?
Does unchecking fix the problem for you ? [Yes, no]
Can you please make a test as follows:

I also stumbled over this particular topic a few days ago.
The Provided Collada files '1b Letter Numbers.dae' and '1c Letter Numbers.dae' both can be imported to SL when using their standard Importer. I also checked both Collada files in more depth:

@Daniel (bestdani) Thank you for reporting this.

@Mick Pearson (Mick-P) In blender 2.8 we only have materials. So the Collada Module must treat this reasonably. I have added material support in the 2.8 branch only a few days ago, and for now it only can treat diffuse color textures. However this is not yet well tested. And more material support is coming as soon as the principled BSDF Shader gets some planned improvement (transparency and emission).

Ok, i admit that is a late response. But if possible could you redo the blend file and pack the textures into it so that i can check this issue ?
The Collada module has been reworked and released to the blender2.8 branch. the changes described above have all been added. However there are still some fixes to be done as follow up tasks.
This issue is fixed in Blender 2.8 - beta (or most recent developer build)
