Cannot heal with serendipity ring

Wicked Bug Reporting
1

Hi, I’m currently experiencing a game breaking bug, I suspect it is related to the serendipity ring, which makes heal over time instead of instantaneous. Sometimes for no reason, I cannot heal, if I use another consumable before the heal over ten second is finished it will be the same. So when it happens on a boss I really have to make sure to survive 10 seconds waiting for the healing icon to disappear before I can use another heal. Without even talking about the fact that you loose the food and a hunger stack.
I managed to reproduce it probably 10 times in an hour.

It happens on Windows and Linux.

Here there should be a recording of the bug + the log files:

You can see at the moment of death lots of numbers happening at the same time on the body.

In the video you can see I was under a plague debuff, but it sometimes happens with nothing so I don’t think it is related. It also happens with various types of food.

edit: I just got the problem with 2 food items in a row, in between fights. So it is also still present in hotfix 2.
