Just confirming steps. Ah, yes. Requires the presence of an LCB. It was used to attempt to clear a POI taken over which shouldn't have been based on community rules.

 

[NullReferenceException when logging off immediately after doing a chunkreset on a RWG tile]

Thank you for sharing. This also corrupts the whole region where the chunkreset f is performed on a dedicated server, and requires deleting the region in World Saves. Tested this twice on two different dedicated servers with the first in A21.1 Stable and the latest in A21.2 Exp.

[Vehicle acceleration inconsistent if picked up regularly]

Acceleration is slower in A21. Based on A21 update notes on vehicles, this is intended.
As for the bug mentioned, where there is retention of acceleration that is beyond a 'rolling' start when getting 'on' a vehicle for a subsequent time, this can also be seen in the Minibike.
