But it shouldn't get outdated, the last patch was in preparation of HH, and for that NVSE has been patched already.
Was it? I thought it was just for the reasons they stated. Didn't pertain to anything HH-related from what I've heard.
If I do think about it though, if you factor out the fact that the .esm got updated, which is in essence, 99% of Patch 1.3, then that would leave the update size about the same as the Dead Money patch.. I think.
