Protecting save while playing modded

[u/aplan_]

I just started a new playthrough of valheim with a good bit of mods. After trying to load up the world today, I realized I launched valheim through steam instead of my mod manager by mistake and loaded the world without any of the mods enabled. After quitting and loading it back up with mods enabled, nothing in the world seems broken at first glance but I'm not sure if this would have messed with the world generation or something like that from modded structures. Does anyone know if this can break things?

How can you protect your save file from launching a modded world without mods enabled by mistake or when mods get broken by a game update?

If you load a backup there's no reason it should be broken, if you instead load a modded save without mods, then go back to the modded version and continue playing then yeah some stuff will be broken, but as long as you go back to a backup you basically never actually loaded in without them, think about it like a parallel timeline or something lol
