**System Information**
Operating system: Gentoo Linux
Graphics card: RX 480
**Blender Version**
Broken: 3.2.0 alpha, as of 1 day ago
**Short description of error**
When geometry is combined with the Join Geometry node in the node editor, vertex colours are deleted.
Without Join Geometry: {F12964563}
With Join Geometry: {F12964565}
**Exact steps for others to reproduce the error**
Create an object.
Assign vertex colors to it.
Use vertex colours as input to color of material.
Use geometry nodes to duplicate the object and join it to itself. This also occurs when importing objects with the object info node, which is how I discovered this.
