### Summary Whether in Editor and Private Version, server consistently crashes several minutes after Verse is used to create a temporary instance of material with a parameter, and assign it to a temporary prop. ### Please select what you are reporting on: Verse ### What Type of Bug are you experiencing? Stability ### Steps to Reproduce 1. In Editor, create a Material that has a Material Parameter node, e.g. `M_Test` with a parameter named `Opacity` 2. In Verse, create an instance of this material, e.g. ```verse Material := M_Test_material { Opacity := 0.1 } ``` Do not store this instance on the device. 1. Assign this material to temporary spawned prop (Not sure if this is required to reproduce, haven’t tried without this): ```verse Prop := SpawnProp(...) # Any asset Prop.SetMaterial(Material) Prop.Dispose() ``` 1. Run your game 2. Wait 3-10 minutes (after material was used). ### Expected Result No issues ### Observed Result ```auto [2024.08.30-19.33.24:737][217]LogNet: Warning: UNetConnection::Tick: Connection TIMED OUT.

I assume that crash might be related to server garbage collection (when material instance is collected), which would explain why timing is a bit random (3-10 minutes), and why it does not happen if material lifetime is extended by storing the instance. ---
