If there were a 5-7 block extender and you increased the number of animals, it wouldn't make a difference because you could only fit a certain amount of sheep in that area before they despawned like usual.
That's just what I think anyway.
well a 5-7 block radius around the player is what i figured the average size of a pen would be like a 10x10 or 14x14 rectangle
point is at the moment i can't get more than 8 sheep in that large of a space and to farm wool efficiently where after shearing the last sheep another one has eaten grass and regained his wool u need about 20-25 to get a semi constant farm rate, im not trying to stuff 100 sheep in the pen, just enough to keep shearing till my bags are full, which really isn't all that big of a request, otherwise im sitting there for an hour and a half for not even 2 stacks of wool. it makes building something like a dragon statue quite tedius and time consuming (more so than it already is)
since a 10x10 area is 100 blocks if it were 1 sheep per block, im only asking for 1/5 to 1/4 of the space worth of sheep, and that really isn't a lot. not to mention after farming/leaving they would just die off anyway since it would default back to 4? max in a 4x4? space.
i suppose the real issue is that the ai on sheep sucks and they like to huddle together and get removed by the plugin.
