That’s definitely not a good mod load order… 
Because it doesn’t contain any of my mods 
But yea, what @darthphysicist said above, if stuff is “missing” then that could be a cause, yes. It could also be a basegame bug being amplified by the added loading times.
In any case, in general regarding modlists the approach should be the good old “If it aint broke, don’t fix it” 
In your case you do have some issue which is quite a good reason to troubleshoot the load order, however if you add your mods in whatever order you do… and you find that it works okay, then just leave it be.
Most of us try to make our mods as compatible with others as possible so a large number of mods even on your list absolutely do not care where they are on the load order, which is a good thing to keep in mind.
Other than that the game loads them from top to bottom, so if 2 mods change the same thing and the “thing” in question is something that is a static asset like data regarding basegame stuff, the one further down will overwrite the one above it.
For example the Iron Broadsword can only have one damage value (provided you’re modifying the base game one and not creating additional copies), so if a mod changes the damage of this sword to 50 but another one further down your load order changes it to 20… then when your game loads that sword will have a damage of 20 because the mod further down the list changed the same value after the first mod changed it.
That should give you an idea of how to move things around if something doesn’t work that you would expect to. You’d move that mod below one that you think edits similar things etc.
