Okay, time to speak up. Hoping to shed some light on the whole situation. Let's start by listing people behind the second grinder. For science.
Now, no longer than a week ago, people started reporting end grinder issues. Due to a fact I was redesigning the grinding chamber back then, I've happened to be around and get a portion of backlash the situation has spawned. The grinder was, in fact, spawning NOTHING and that's where I went into detective mode. Noticed Redigox on the mainland and pointed it out in global chat. By that point, Redigox was perfectly aware of the second grinder (since he's the one who made it, of course). He chooses to pretend he doesn't know about it and act like a derp: And when he's done grinding, arrives at the main "Seneca" grinder to play dumb some more: Few days later, a user that would like to remain anonymous has informed me of the other grinder and even gave me a nice tour. Mandatory imgur album.Fast forward to present. The topic of multiple grinders arises in chat where another person and I point out there are, in fact, already two. Shitstorm ensues.
Turns out Vinhaven is not as cool as it seems and there are some other grudges being held against it, which I don't really know of. Surprisingly (or not so), both situations involve that person. It's safe to assume people who've built the second grinder knew of the one-grinder agreement, otherwise they wouldn't make it hidden. My point: one grinder to rule them (endermen) all. Let's just have it as a rule. It's not "Seneca grinder" and you don't have to be a Senecan to get building permissions there (best example: me!), so please take that S mentality of "private grinders" back to S. This is P and people are expected to share things. Keep in mind "Atlantis and vinhaven residents only" signs don't really conform to that.
Who would've thought addition of hoppers could reveal so many things about people's personalities. >:P
