It's not legal to have huge amounts of animals last I checked. The rule is written next to the egg vendor at /warp grass, unless it was removed. So, perfectly allowed for a mod to /lagg them. ^-^ If this happened this morning, I still couldn't log in for about 4 hours, untill the server count had died down. I really don't know the cause of this issue, but I feel like it may be unrelated to the recent lag...
takes the point out of spawners, and would need to install a new plugin... work,work,work see wouldn't work and if they just made it a rule it would be too hard to enforce
