Bound thralls disappearing

I have a base near the Black Hand base, close to the Sand Spit. I’m getting a bug where anytime I drag a thrall across the stone bridge over the chasm inbetween the two POI’s, it’ll disappear once across, and the binding rope will stick to a point on the ground. Interacting with my Wheel of Pain will remove the stuck tow rope, but the thrall doesn’t appear in the wheel inventory. So far it’s happened anytime I try to capture a Black Hand pirate from the main base itself

its not just the pirate base. its happening to me everywhere. I haven’t been able to get any thrall since the patch. I even have a wheel of pain just outside the stygian base and I cant even go that far before they disappear
