You can tweak as you go but general stay away from major overhaul in the middle of a play through. Good rule of thumb is to pre-determine what mods you want for a play through and stick to those for the entire playthrough. I have not had this happen yet with FO4 but it has happened with Skyrim. Installing and removing mods in and out of your load order could cause your save to fail. However, this feature is finiky at best but at least it is something.Īlso, be aware that you will probably spend more time modding your game than actually playing if you are like me and you constantly moving mods in and out of your load order. NMM does have a feature that will allow you to see if your mods have been updated as long as you hit the 'track' button on the mods description page. You want to make sure that you get the most up-to-date version of your mods. Understand that there might be mods that no longer work, crash to desktop, because the program got updated. As Cryzeteur says it is a safe way to go but honestly, I have never done this and I have yet to experence a major with my save file after an update. However, that issue seems to have been resloved. There was an early issue with NMM and 1.5 and the 2 not talking very well with each other.
