I recently started a smite paladin build and once I enabled the javelin’s surprise initiative ability I discovered that dropping the javelin out of bounds and then triggering the Dash to Flag combo causes the character to freeze mid animation (where there arm is pointing forward like they are just about ready to dash) and are stuck in place. Once they are frozen mid-animation like this the only way I’ve found to unfreeze them is to cast rebuke or to exit the game entirely.
I’ve tried to be extra careful to drop the javelin within bounds but it’s pretty easy to just barely be out of bounds in the franticness of a big battle that’s happening right up against a wall or barrier. It’s a big enough issue where it could mean certain death by getting frozen and not being able to move or break the freeze if rebuke is on cooldown, especially late game where life or death is sometimes a second or two decision. Keep in mind I only play HC so it’s an even bigger issue in that case.
