Shout-out to Guillin and Blaten in earlier posts.
Using both their comments, I was able to make things work and wanted to share my experience on how I fix mine through Vortex.
In Vortex, on the side tab menu, under "Oblivion Remastered" is the tab "Load Order"
This is where you need to arrange the load order as per Guillin's post. Make sure to untick all your mods and arrange these as the list in the quote.
However Vortex will add two files as per Blaten's post.
AltarGymNavigation.esp
TamrielLeveledRegion.esp
Those two are fine to keep just make sure they are at the bottom of order from Guillin's post.
Now add your mods in and make sure they are after Guillin's list (extremely important!) This will set you up for getting the files loading correctly however still might not solve your problem.
The "nail in the coffin" for me, came from some mods adding multiple files into the mix, example standard/deluxe edition.. my recommendation is to untick all mods and tick those with one load file. Those with multiple make sure to only tick the one relevant to your edition. You could further go by ticking one mod, running the game and seeing if it works. This will definitely make sure you know which file is corrupting the order.
Thanks again to those before me whom assisted in getting this right for us!!
Now I'm off into the world, only to be reminded that many have fought mud crabs more fearsome than me!!! LOL
