Animals escaping the fence.I made a animal farm in equinox easy survival world but everytime I rejoin I find animals not in fence and roaming around. There is no block from which they could escape.

i made my base on an island which is very small. i made a small animal farm and there is enough space so that animal could fit in easily. but every time i rejoin game i find them not in fence and roaming around in my island. my animal farm was a simple one. i know some people would tell me tht u would have place block inside fence from which animal escaped but let me tell them i did not place anything like tht. the farm was simple. it consisted of spruce fence and 3 gates. i checked it clearly tht there is no wasy tht animal could escape but still they are. PLS MINIBLOX TEAM OR ADMINS HELP US.
