Hound Master's Dog & Vault glitch.
SUMMARY OF THE ISSUE: In another bug report, it was stated that the hound master's dog can vault windows that are too high. this is currently true, however, I found a new, game-ruining bug related to this. The only instance of this that I've found, is in Crotus Prenn Asylum. (Specify the version with the church.) In the video I provide. (Sorry for why it looks like that, I messed something up.) You can see that once I order the dog to vault the window that is too high, it phases through the wall, and because there is no solid floor on the other side, and the game wasn't programmed with the dog in mind, he will fall into the void forever, preventing him from being used for the rest of that match.
PLATFORM: PC. (It will probably happen on Console, not tested, however.)
STEP BY STEP INSTRUCTIONS ON HOW THE ISSUE OCCURRED:
Pick The Houndmaster. Pick the map: Crotus Prenn Asylum. (Specially, the version with the church.) Go into the main building, use the Special Ability: Chase. towards the window that is too high. (An example of exactly that is provided.)
