Other than those 2 situations I haven't really had any of the issues you're describing. Horridon does have a very large hitbox, if your pet is on him and then you swap it to adds, it might take a fair amount of time for him to get there (esp depending on where you position horridon).
Not sure what you're saying on Qon at all, was it you could just never KC again after Tornado phase? No idea what would cause that. If it was just that your pet is missing while he was on the side that a shield is... well... yeah, that's how the fight works...
