I haven’t tested this new patch yet but since it’s not mentioned in the patch notes I assume the bug where thralls vanish is not fixed yet?

It has been reported in multiple threads over the past few days, e.g.

/t/thralls-falling-through-floor-post-27-04/3526

/t/thralls-in-tow-disappear/3580

/t/thrall-falling-under-terrain-when-dragging/3578/2

(seems like I can’t add links in my posts for some reason…)

I’ve been experiencing this bug on Testlive as well for the past few days so I would guess this bug was introduced with one of the recent Testlive patches. Not sure which one though.

This happened to me on dedicated servers, single-player mode, and coop mode. And basically I haven’t been able to capture any thrall since then.
