[OpenSIPS-Users] Problem with fix_nated_contact

I'm using OpenSIPS 3.2.4 and recently run into following issue:
Imagine simplest proxy setup - OpenSIPS just accepts new packet, for
example INVITE, changes destination using 'sethostport(....)' and then
issues 't_relay()' to forward the packet. Let's ignore replies and so on.
If I'm doing a 'fix_nated_contact()' before sending this packet I'm
expecting Contact: field to be replaced with a source IP:port as per
manual. And this works if the Contact is in simple form like '
sip:7777777 at 192.168.29.106:65033'.
But if following Contact comes in OpenSIPS doesn't change it leaving
private IP in the contact:
'Contact: sip:7777777 at 192.168.29.106:65033;rinstance=2f59b175103f1088'
Can you please let me know why is that happening? Thanks!
