I will not be using the format, as i do not know how to replicate this bug, or how it works, but i feel it should be reported. At the spawn area, some people are able to place blocks, this is under rare times, I believe it has something to do with the worldguard plugin, however it could also be a different plugin Videowiz92 was looking into this for a good amount of time today, maybe video has a bit more info. Screenshot:
I was there, I managed to destroy one of the blocks. I just kept trying to destroy it until it disappeared, I did not receive the item.
No, they blocks are in a worldguarded region, meaning normaly they shouldnt be seen, especially since users can destroy them, and all users see them, however a restart may be able to fix the issue. May be visual glitch, ill talk to video, maybe video knows if that is possible.
I thought this might be lag, and after relogging it was gone. However I could hear chat and see people move, so I wasn't severely lagging.
The staff team knows of this bug and are looking into it, when you place blocks, make sure they are actually there, by having someone else see them, or by re logging, as yours, phiphiphi, was just a client-side bug. As for that "Abstract sculpture" that was next to the Nether portal was real. If anyone has any direct information on exactly how to reproduce it, it would help, but until then, the Staff team does know of this bug and is looking into all ways it can be caused, and the true effects of it.
