Hi, I use a Killer Joe in my mob grinder to get mob souls. The problem is that sometimes when I go offline, it apparently crashes the server and I received a notice saying not to place it again. I just wanted to ask and see if this was a set rule because having the Killer Joe boosts my progress quite a bit.
If you are placing a killer joe and crashing the server, then were asked not to do it.. then yes don't do it. It is unlikely that it is the killer joe alone that is crashing the server, but rather the way you have it setup. I'm not sure who responded to the crash so I cannot provide you further details.
I had draconic spawners and a wyvern sword with reaper 4 in the killer Joe. I also had a wireless charger keeping the sword charged. It was never a problem when I was on the server but apparently it sometimes crashed the server when I was offline
