Autocleaning update.esm and all dlcs with SSEEdit fixed my CTDs?

[GRASSES ON]

So I'm really new to modding and I was constantly crashing not too long ago, even after fixing my load order, and even though that helped I was still crashing from time to time, so I saw some recommendation to install SSEEdit and use the autocleaner to clean the main files of the game and I'm not crashing anymore, does it make sense for that to happen? What does the autoclean feature of SSEEdit even do? thanks

Skyrim plugins can contain several kinds of errors. Unfortunately Bethesda made a horrible job with their official plugins regarding such errors, as all of the official masters contain numerous errors which never got fixed. The xEdit utility offered us a way to clean such errors from any plugin files, including mods and the official masters. The autoclean feature simply offers an easy way to do it automatically to the official master files since their errors are well known. There's no need for individual users to do it manually, making potential mistakes in the process.

The notable kinds of cleanable errors present in plugin files include:

1) ITMs, or "Identical To Master" records, which are records that are the same as a record in a plugin's master file, often skyrim.esm. For example, a master file could include an object in a specific cell and a plugin could contain that exact same object. The problem with this is, if another plugin is supposed to make changes to that object but the mod with the ITM is after it in the load order, the ITM will undo that change which can often cause problems ranging from misplaced objects, script events not working, missing textures or even broken mesh references which can cause crashing.

ITMs are the most common type of error, and even the official masters have over a hundred of them. Probably the most well known one is the Breezehome upgrade bug, caused by an unclean Dawnguard.esm, which can cause the steward to take money for an upgrade but the upgrade is never applied to the house.

2) Deleted references. These are a significant cause of crashes and game bugs. When a reference is made and then removed, it remains in the Creation Kit as a deleted reference. If another mod then tries to modify that reference, we have a problem. A deleted reference can be fixed by undeleting the reference, disabling it and moving it to a position where it is no longer visible in the Creation Kit or in-game. This has the same effect as deleting the reference, without causing issues.

3) Deleted navmeshes. A similar problem, but for navmeshes. Like deleting records, deleted navmeshes can cause crashes.

So TL;DR, does it make sense for cleaning to reduce crashing? Yes, because the official masters contain all of the above problems and never got patched by Bethesda.

Thank you :) that clarifies a few things
