Guild Wars 2

So I was exploring Lions Arch to see what changed and headed to the Vista with the jumping puzzle. My character disappeared in the ground and I realized the ground wasn’t against its bottom layer. You can’t fall through but it’s definitely not right

Found another in LA

You can walk through the terrain west of Fort Mariner as well, when you approach the lighthouse. People are calling it “Sand Swimming” since you can walk through the sand.

Forgive the quality, was having odd performance issues and had to turn down everything.

There are also some rocks very near to the sinking sand that your feet disappear into.

I noticed the “sand swimming” as well.
Overall I really like the new Lion’s arch and what they did with it. Giant chunks of wreckage from a prior battle that I was in… That’s the kind of thing I was thinking of when they mentioned dynamic changes to the environment.
