After putting in a hefty amount of hours in the last few days since i started, (with no freezing or crashes), my client just froze, within the first 2 minutes of entering the game after today's patch
I feel your pain. I started the update a few hours ago and it crashed. Now, I've been trying to re-install for more than an hour. Download 0 -> 451. unzip. rinse. repeat.
The most common issue I'm seeing in this release is loading scenes, so I'm guessing it was that. Thanks for posting feedback, but it is more likely to be seen by the devs if you post in the R32 feedback sub-forum as opposed to General Discussion.
FYI there is an official bugs section of the forums. This would look great in there! Just in case you people didn't notice them.
