[Headless] Mass delete hangs server

[zedle]

When mass removing parts of a factory we've had the headless server (not sure if it happens in normal run) just stop responding to anything. Control-C'ing it still reacts, but stops when it gets to 'saving last exit'.

Let me know if you need any other details.

Do you have the log file from server?
Edit: Some players report that sometimes clients using F3 area delete by BlueprintTweaks will hang server.
If you are using BlueprintTweaks, try to disable useFastDismantle in its config file.
