Hello EMC, I have created this thread upon request (by iLikeMuffins11) so she can figure out why her sheep are escaping from the pen. The sheep are penned in. There are no fence gates. I use the RTS to get in. There in no RTS out. Screenshots...
The sheep somehow are able to jump on each other and then jump out. I would make the fences 2 high and put on a roof.
Dokucraft revival. Hasn't she heard that mobs are VERY buggy in multiplayer? You need flowing water to keep them in their pens, otherwise they'll glitch into the walls and never come back out.
Texture pack is Dokucraft High. Here is the link: http://www.minecraftforum.net/topic/513093-32x16x132-dokucraft-the-saga-continues/page__st__0
Fences to keep sheep in should be at least two high and two thick to prevent the sheep from glitching out of the pen.
