Sempai, I reduced the warnings count from 98 to 0. Figured out what were that 'track' things and got rid of them successfully:
Never call me Sempai again. I find it gross.
Didn't know that vanilla models have such problems as well, like Peon or Rifleman have tonns of errors.
Yes, I was using RMS.
I have significantly reduced the number of unused tracks in each model, leaving only a few that make the model lie motionless after death.
I would have preferred that you'd fix the animation instead of deleting it, but I guess in the future you'd probably will be able to do that too.I have significantly reduced the number of unused tracks in each model, leaving only a few that make the model lie motionless after death.
I left the second portrait with the hard helmet with negative extents because it is a clean copy of the initial portrait that does not have negative extents in the same geoset (somehow), besides, as GhostWolf said here, this case does not affect WE.
Fixed the Stand-3 animation by deleting it.
Retested all the animations, checked the models in game, re-uploaded the files.
Yeah, sometime later I figured out how to fix it, but was too late
I believe, it's about momentarily changing the size of the pickaxe, or am I wrong? 
It has less than the regular peasant model, but the artistic choice is yours.Yeah, sometime later I figured out how to fix it, but was too late
Anyways, the model still has enough Stand animations, so I thought that deleting it would be ok.
I politely disagree. Dwarfs have quite big work-weary hands like on this picture from WOW and this art. They are also quite stocky compared to the rest Warcraft 3 models. If you use your Scaling Value correctly (just to make their heads look the same size) you will see the point:
You are totally right on that.
I wasn't referring to the limb and body width/thickness but to the fact that dwarves have shorter limbs as you can see in the WoW screenshot you linked.
Yes, they don't have consistent proportions, that's why when you make it custom it looks ok. However, I've changed the proportions and you can make your model even smaller at any time.
Well, it's a matter of taste of course, but there I intended to make almost a vanilla unit to get a feeling like the model was always there in the game, just like I noticed in the description.
For me this detail makes it quite original as no workers have team-colored heads plus they don't have a flashlight 
That's fair, but you cannot that expect it to be put in simple/useful category.Well, it's a matter of taste of course, but there I intended to make almost a vanilla unit to get a feeling like the model was always there in the game, just like I noticed in the description.
Thus, I wanted it to have WC3 Dwarven details to make it a part of their 'army' like they have almost the same uniform and I was trying to use only regular and 'signature' parts of the game like another variation of light armor. At start, I wasn't even sure about the hard helmet
If you say it doesn't look unique enough but fits nicely then my goal is achieved
It's ok
But if you let me I wouldn't learn so much for sure 
I didn't let you edit it and upload it because I don't know you. I aslo think doing the hard work yourself is better in the long run.It's ok
That's why I asked your permission to change your Dwarven Axethrower model because for me it was a perfect example of a lore-friendly model
True.
That is a very honourable aim and I fully support that.
Thank you!That is a very honourable aim and I fully support that.
I'm using RMS as well. Hmm... Try this out, different format.
You should start uploading version 800 mdx then from now on.
It works!
Probably because the former model was broken or a format 1000 version model.
