There is a setting in OBS Studio under "Settings > General" labeled "Automatically record when streaming". I don't know if that could have been tripped off accidentally at some point, but based on your description I'd say that it used to be enabled and now it is disabled. Although, since you said that "my streams used to save after and I have never messed with any setting since then and now they dont save anymore", I'm not sure why the setting would have become disabled if that were the case. Food for thought.
As an aside, you're using OBS Studio 0.14.2 and the current version is 0.15.2. I don't think it's relevant to your issue, but thought I'd mention it nonetheless.
