Not sure if it's intentionally missing but I'm missing damage direction indicators.

Got this error when shooting someone in the head:

[Generic] Exception when calling 'Update' on Player
System.NullReferenceException: Object reference not set to an instance of an object.
   at HitMarker.CreateFromTrace(SceneTraceResult tr) in UI/HitMarker.cs:line 61

EDIT: Also someone physgunned me out-of-bounds and it didn't kill me. Couldn't type `kill` in console either to respawn.

It's rumored that you will be able to pull assets from games installed on your library.

Will this be available for Sandbox Mode?

- When someone leaves the game, it puts the "has left the game" message in chat once for each person left on the server
- Using resize tool on players is fun, but from the perspective of the player who was resized, they appear to be normal scale the entire time

Swapping to a tool from the spawn/Q  menu and then using the number key to swap to the physics gun starts cycling through from the tool gun (so you need to press 1 twice to get to the physics gun instead of just once)

- You can only hear other players Voice through the left ear
- When flying (double pressing space) you'll almost always die of fall damage when you double press space to exit flying and land on the ground (even if you only fell less than an inch)
- Cloud Props spawn as an error model at first, and then load into the real model (instead of showing a loading placeholder or something)
- Got this error when someone was going wild with physics objects:
- Chatbox and Health UI are still visible when using the Camera
- Can't use :emojis: in the chat
- Can't press R to unfreeze all attached objects in a weld
- Servers are named "Sandbox Deathmatch" instead of "Sandbox Game" or "{name}'s Sandbox Server"
- "has left the game" message shows even if the player never connected in the first place (eg. when cancelling the connection to a server)

Ropes go crazy after alt-tabbing into the game - and the visible slack on the rope does not represent how taught the rope is.

If you duplicate an object attached to another object with something like a rope, the duplicated object will also be attached to that same object with a rope. It's cool but not sure if it's intentional

Seems to happen when using the wheel tool and trying to place it far away

attaching a wheel to an object makes the physgun freak out and apply impulses, should stay still like when it has no wheels attached right? (both are shown in the video)

I know it's early stages but it feels like it's already shaping up to be something great. Physics feels really good with most tools already and work as expected. Even with people trying to break things as much as possible everything still looks and feels really responsive. Going to be exciting to see it shape up over the coming months.

Not really an issue on the game, more like an issue on the forums. Trying to play any of the above videos displays the following error and it wont continue:  (I am on firefox windows 11 BTW)

If you noclip too fast trough the ground u take fall damage, also when in noclip you collide with props enabling some weird thing when passing through props while in noclip.

The tools do not always work, and even after some point, the prop stops spawning (retry doesn't work). Regarding Noclip, it's not very convenient on double jump, it's better to press the (V) key as usual and make a slight improvement: when you press the space bar in Noclip, you fly straight up, and take damage in Noclip by the walls.

Mounts only work the second time you load the game

The vignette is a hard yuck from me to be honest. Its tolerable on my big monitor but on my slightly smaller one it just feels so strong and gross.
 also it doesnt look like theres any tonemapping and its just set to linear? 
the visibility of the HUD is also pretty crap, guess this was harder to notice in SBDM because most of those deathmatch maps are dark and indoors

This is a pretty strong foundation already, can't wait for it to be complete/ready for people to add their own stuff onto it. 
I think designated folders to load models in S2/sbox format would work good too since that's what people from S1 are accustomed to, although I was told on discord technically could just put them in base addons which I suppose still works.
One thing I noticed is that rotating ragdoll bones with a physgun and whatnot can become quite fidgety randomly/go unresponsive to E inputs but hey it works for now.

Just jumped in, damage UI image still appears to be missing for me, but the new vignette looks so much better!

I also get an error when trying to weld an object to itself.

Physics gun glow from a distance feels like a bit much to me, but I'm not sure how it was in gmod.
