Try
/deleteplot roseville cheststore

That should do it. You separate the town and plot name for the delete command and case is important so all lowercase.

 

Since that got an informative here is what I learned and what I've seen.

/rg is forgiving about case,I but it is all lower case with tc commands...always. if you type it with caps it gets converted to lower and then won't recognize it later if you use caps.

The /rg command smooshes town and plot together to make the name, but create and delete plot separates them so it knows what town to do the work in. My guess is the entries are listed as children in the DB, but it doesn't really matter as long as we say the incantations right.

 

You aren't the first to ask this... Just the first on here. Glad it worked!
