I am sure, but it does not fail every time. Please first apply the building area and then cancel it. The building cost will still be displayed on the right side. At this point, clicking to close the UI display or typing /COST will cause it to not display. I hope it can automatically close when the building area is canceled.Additionally, I hope more language file content can be added. Some prompts, as well as switches, windows, and shooting holes, still require me to translate them manually.
