Entered a ticket #89634556. I’ve removed all addons, renamed files, scanned and repaired, changed interactive to non-interactive and back on my chat options, everything support asked me to do.
My main Dracthyr (lv 70 dev) cannot link mounts in any chat.
My other toons can
My brand new Dracthyr can
People in the facebook group (35,000 players) have also reported their lizards cannot link mounts in chat though some can. To date, no non-lizard has reported in my post that they cannot so it seems to only be affecting Dracthyr
