In Version 1.5.0.10 (and previous beta 1.5 versions) dogs that I previously had in my worlds will not stand. I can feed them and they do the hearts animation, I can kill them, but I cannot make them stand.

In previous 1.5 betas this affected all my worlds. In 1.5.0.10 I can now make my dogs stand (in at least one world) that does not have the Experimental Features enabled. When I enable experimental feartures the dogs are affected.

Newly tamed dogs work as expected, so it's not that I forgot how to interact with dogs
