I made a similar post about this issue a month ago. Unfortunately this issue is still present in the warrior priest update despite this issue being acknowledged by the fatshark team. Which is surprising since I would consider this a major issue.
I am aware that another gromril related bug has also been found, however I think this one is independant to that because this bug still occurs whether I am hosting or joining (ie: this bug still occurs even when gromril armour is activating correctly).
Here is my video proof of the issue.
