Think I've found the bug when going through the host json settings log. I'll add supporting data at the bottom but would appreciate clarification.
My constant announcement spend is due to Siac switching IP address' between my IPv4 and IPv6 address (even though I have a static address). I have no idea why every couple of hours it is unhappy with the previous settings it chose, but none the less it's gleefully spent a few thousand Sia for me, as each time it does this it sends a new announcement.
As a temporary fix I've disabled IPv 6 in my windows network adapter settings, (as I need to use ipv4 to connect to other devices on my network through my browser) but are the developers able to implement a more permanent fix. I'm not sure how many others this will affect in the future, but can siac only recognise either ipv4 or ipv6 to resolve any future conflicts.
Regards,
Dan
Below shows the host log constant entries switching between IPv4 and 6. It is just a snapshot as the whole file is very large. It's in it's origional formatting with newest entries at the bottom.
