Hmmm, Here I am again...

I've been moving back and forth trying out 6.0+ the questions I have are concerning backward compatibility.

Synopsis, I had been running 5.1b6 for a while, along with 210 (esm/esp) in the mix. Tweaked ran flawlessly. When I update to 6.0.0 I moved back due any mod which used arrays went crazy with errors - I think counted 14 of them rendered useless or unstable enough to cause flaws in cosaves or even a ctd on a load of a save created under the environment, So, moved back to continue play from an old save, then slowly as 6.0.1 through 6.0.5 - at 6.0.5 I was down to 4 mods misbehaving.

So, 6.0.6 was released - and what I got then was after upgrade, a load-up of a save produced under 5.1b6, then a save under 6.0.6 and reloading those new saves going forward - mods complained of missing cosaves - although the files are there, that did not happen under 6.0.0 through 6.0.5.

I think I was having a simular issue when updated my NVSE version, I was having bugs to creatures that used SetObjectHealth and also GetEditorID stop functioning but that is JN NVSE related. The mod that I'm working with adds weapons, armor, NPC, creatures, etc. to formlists then tweaks them with conditions. I checked the mod page for SetObjectHealth and I noticed the it has been edited on 3/3/2021.
