A week ago I bought an explosive pickaxe and never received it. I posted about it on the forums and the server owner posted a reply fairly quickly so I thought it would be resolved just as quickly. NOPE, nothing but silence since then. With this and the posting about the same problem in general discussions there is some evidence that it's bugged, buyer beware.
Nope, it's been two weeks now and not a thing has happened. Early on I did try contacting the mods, but the response was always the same, sorry can't help you, post it and hope someone who can will notice. The server itself is enjoyable, but the staff repeatedly stamp out any possibilities of me trusting them.
