Ive noticed that //up no longer is able to be used. Please consider replacing it because its helpful for building houses and tall structures.
indeed //up is queit convinient, but i think it is disabled because of some sort of glitch that was happening but i dont know for sure
what you do //up 20 it places a glass block and that can be used on plots to replace blocks on others plots
Technically, yes, but it's a glitch, and somehow you can do it on any plot. Or at least it worked last time I checked, that being around 5-6 months ago.
