When there Is one OR MORE dead players, zombies or animal in say a doorway, its very hard to get past them you have to jump and wiggle your way through and only sometimes you can get past.. you can get stuck behind it, unable to exit that particular doorway. This i'm sure is a simple fix, you just need to be able to walk through a dead entity, Or a ragdoll entity. By this i mean when something dies you should be able to walk through it.
