Known issues

Due to a combination of engine limitations, small scale development, and its alpha state, HDR has many issues and bugs. The following is a list of known issues that the team is currently working on. If you do not see an issue listed, please report it in the Discord server.

List

 * For various reasons, characters can randomly freeze in place or form a T-pose, though it is rare. The spring platforms on Spring Stadium will consistently force a T-pose, though the character remains actionable. Report specific instances to the Discord server.
 * Throws have not yet seen many changes from Ultimate, and issues can arise with some of them, such as with Lucas's down throw.
 * It is possible for multiple characters to grab ledge on the same frame, ignoring ledge hogging.
 * A few moves can ignore stage geometry under certain circumstances, such as Jigglypuff's rollout.
 * Wall-riding, such as when using a teleportation recovery or Lucas's PK Thunder against a wall, does not always function as expected.
 * Matches that include multiple of the same character are plagued with issues, and are generally not recommended. Reportedly, this is more egregious with some characters than others, such as Captain Falcon.
 * Some projectiles can spawn duplicates if the character hits the ground while using the move on certain frames, e.g. Wolf's blaster and Dr. Mario's pills.
 * A few projectile moves, under certain conditions, can cause the character to permanently float and allow them to move horizontally. Fox, Falco, and Wolf's blasters share this property.
 * Projectiles can sometimes disappear when interacting with platforms, reportedly more often than in Ultimate. Naturally, this affects larger projectiles like Samus's charge shot the most.
 * Some articles do not spawn correctly, like Isabelle's forward smash and up smash.
 * Various hitboxes can linger for longer than intended - Lucina's shield breaker is an example of this.
 * The hitbox visualizer in training mode does not always function correctly, and does not work with animations that use bone scaling, like with many of Piranha Plant's moves.
 * Animations in slow-motion can often result in errors. Characters that use imported animations suffer the most from this, such as with Dark Samus.
