Notes: I am 100% sure that cleaning is the cause; after reverting to a dirty plugin, the soul cairn worked with no further issues. I used Gopher's guide on how to clean master files, I have attempted two separate times to see if I did something wrong, according to the guide, I did not. This issue has been presented on other forums, I have found no solution other than retrieving the original dirty plugin. This is my mod load order. Also of note, I cleaned SMIM because it had a deleted record, I Only cleaned the ONE record, I did not deleted identical to masters, as there were none listed by loot. I believe that cleaning with Gopher's guide may have deleted something that shouldn't have been deleted, if so, where can I find a new guide on cleaning the masters? Most links I've found are dead. Also, what exactly is being deleted that is causing this issue? And most importantly, how do I clean my dawnguard.esm without causing this issue?

I'm aware it's possible to convert mods from Oldrim to SSE, though I'm not so sure if the reverse is true. Is there a limitation on which mods can be ported? If so, what types of mods? For Example, if it is possible how do I convert a mod like High Poly Project from SSE to Oldrim? Apologies if I am posting on the wrong forum, or am in violation of a rule, it is unintentional.
