Reposting this from the Steam forums in hope of that these issues will be resolved soon.

cs_assault:
- Prop_Physic_Multiplayer: There are many offenses of Prop_Physic_Multiplayer props with player collision turned on, many props, such as the multiple "traffic_barrel.mdl" models around the map which would be much better off as Prop_Static models. (This would also help improve performance.)
Many of the smaller props, such as the smaller cardboard boxes would be better with just player collision disabled; however the many larger models such as the chairs, wheelie bins, barrels and filing cabinets need to be turned into static props.
Since the last update the filing cabinets have been changed so that they don't move however they still repel players who walk near them which can cause a lot of issues.
- Visible nodraw texture: There is a visible nodraw texture on the corner of the street near the containers.

- Model clipping: there are multiple instances of “drug_pallet04.mdl” clipping with beams on the warehouse floor, in these instances please replace the “drug_pallet04.mdl” model with a smaller model that doesn’t clip with the beams above, such as “drug_pallet03.mdl” etc. Image 1

- CT Story: There needs to be a “swat_van_generic.mdl” or a police car model, visible near CT Spawn, to explain where how the CTs reached the location and how they are taking the hostages away to safety.
- Floating Truck: The trailer in the tunnel is not connected to a truck, the trailer should be connected to something in the tunnel, so that it doesn't look weird or out of place. The trailer wheels also heavily clip with the pavement.

- Navigation File: The navigation file has not been labelled at all.
- Displacements that need to be sewed together: There are a few gaps in the displacements on the pavements that need to be sewn together.

- Bad Texturing: There is an instance of poor texture alignment on the street corner.
