Could possibly be controller drift, it happens to mine when I use it occasionally. As for the freezing, not sure about that... could you post your PC specs?
You mean thiis: "Intel(R) Core(TM) i7-8550U CPU @ 1.80GHz 1.99 GHz" ?
Also, I beat the game as well! Really good, the last two worlds were pretty creepy. Too bad the Hub+ isn't a permanent choice, but then again, if you found the Secret World, there is not much problem with it either.
Glad to hear you enjoyed it! There will be bonuses in the sequel which will save properly, including another hub+ mode. I may go back one day after and implement saving into this one as well. I hope to have that weird controller issue and any other bugs worked out too. Cheers
