Hey.   Its not hard to get FNIS to work with MO.   Make FNIS executable in MO, there are tuorials   http://wiki.step-project.com/Fores_New_Idles_in_Skyrim   >https://www.youtube.com/watch?v=VpOuGN-yr6E   Open FNIS with MO, update animations with arm fix path, and there should be overwrite on end of mod list,right click on overwrite and create mod, activate this new mod and everything should work.

I have the same problem, I think it is because system cannot hanndle all scripts when save is loaded.

When you instal thins like HDT you need to use FNIS and on down of list of mod packages in MO, there should be wrinen OVERWRITE in red letters, click it with right mouse button chose create mod , name it and activate and it should work.   Optionaly you can instal HDT with diffrent mod manager.

Is there a mod that always trigger critical death effect for energy weapons?

If they are selling your mods,then pirate this  "Ning Lou Love Lab" and give this to people for free.
