I will say this carefully to avoid spoilers. I was near The Slog settlement and on my way to the Insane Asylum when I had to fight a Glowing Deathclaw. Ever since then, there is this random earth quaking effect that just wont stop. The quaking lasts for about 2 seconds, then stops. Then 10 seconds to a minute later the quaking happens again. I didn't notice the quaking while fighting the Deathclaw but I wasn't aware that Deathclaws can have a quaking effect until I researched this issue (and because I'm only focused on what I am doing when fighting a Deathclaw). I didn't notice the quaking until a few minutes after I killed the Deathclaw (I had just arrived at the Asylum when I noticed it and thought the quaking had something to do with the Asylum). But the Deathclaw is the only thing I encountered at that time that has the ability to initiate the earth quaking effect which is why I believe the Deathclaw to be the source of the problem. Has anyone here had/having this issue? And if so, is there a way to fix this? I'm still able to play the game, but the quaking has simply become extremely irritating. Thanks for your help.
