When I logged out of STO last night (I am in US EST, btw), STO patched itself. The release notes on that patch were exactly the same, and it was the same size as the patch the launcher is applying to my game right now as I am writing this.
Did this happen to anyone else? Did the patch change from last night to this morning?
Pre-patching puts files that are close to the final release version onto your hard drive, so that when the final version is released, it can copy them from your HD when it patches instead of having to download them in the rush to update to the new release.
in theory - prepatching helps bandwidth and gets you into game faster after a big update like this.
I think something got screwed up because I saw it pre-patch last night and logged in an hour ago to play but it is downloading again. Definitely not just applying data from my hard drive. I can see the bandwidth being used.
