I <p>I think this happens because the dimensions of the creature, some of them creature.</p><p></p><p>There is creaturers that are 32x32, 32x64, 64x64 and 64 x32. 32x32; <img alt="" src="https://www.tibiawiki.com.br/images/a/a0/Chicken.gif" style="height:32px; width:32px">. others 32x64 <img alt="" src="https://www.tibiawiki.com.br/images/c/c4/Mutated_Rat.gif" style="height:58px; width:37px">, and 64x64<img alt="" src="https://www.tibiawiki.com.br/images/d/d3/Bonelord.gif" style="height:64px; width:64px">. And the space for display them on the client is a bit little, I think thats why the creatures doesnt have same size.size.</p>
