Character's HP instantly disappears without any cause

[Silvaren]

I noticed that my Watcher's HP drop in some strange way. My Watcher didn't lose conscious but his portrait turned red. He wasn't at 0 HP but the game displayed it like it was no HP value at all - "    /200", in other words - "empty space/max HP" and "0/200" on the portrait.

 

I uploaded video of that fight:

 

Healing and resting didn't help at all so I reloaded previous save. This bug appeared with Vatnir's HP this time.

I uploaded second video:

 

 

I put save files in dropbox:

Hi, Silvaren. Thank you sending those files along. We'll get an issue entered for this and a fix in as soon as we can identify the issue. Your patience is appreciated.

Thanks for the report.  This is caused by the Eoten's ability "Gutting Strike" and will be fixed in v4.0.2.
