I bought it, used it at spawn and it said it was banned. I then moved back to west and the empty syringe disappeared. Also, mod-eandpi is pretty useless imo, wouldnt even reply to me when I tried to ask him about this problem. OK I dont think I ever knew how to activate fly mode in creative so I didnt know how to activate the fly mode, works fine.
Ok, so, you solved the issue by yourself, but please, do not accuse moderators in open threads. There is a staff complain thread for that. Also, he couldve simply been afk, and i agree he couldve vanished to not create confusion for the players on whether he is on or not, but its not a thing that you should call him "useless" for.
Regardless whether he didn't reply or not, exactly as Kriss said, don't target a player/staff like this in an open thread/chat. You're playing this server for free, and we're volunteering for free, we're allowed breaks now and then.
I really am sorry for not replying directly, but I was having connection issues at the moment of your request, as well as several other people asking for help at the same time. I am only a single person, and there were 2 other moderators online too at the moment. If one moderator is non-responding, please ask another moderator for help
