Horse vanished mid fight while taming

[Izunundara]

Had a horse aggroed, 90 taming progress. Ducked into my house and switched combat deck, and when I used my first sidestep in the new deck (old one didn't have any way of lowering Blue openings oops) the horse instantly vanished. Combat ended, totally disappeared. Seen some other mentions of tamed animals vanishing, but they were related to crossing map grids and I'm not close enough to one for that to be related

You got hit with a wipe tick during the moment you ducked inside, which wipes everything in the area when a character isn't keeping them loaded.

If you're gonna cheese stuff, at least make the effort to have an alt afk in the area
