Bases get almost instantly destroyed

Hi guys I think it showed up after the initial blood and titanium install and still continues in the latest version.
I’m noticing that some NPC bases are getting basically insta-killed, I thought maybe it had something to do with the attacker vs defender ratio, but I just saw it happen with a 10 to 6 rating.
Basically the coloured countdown timer thing almost instantly (sub 10 seconds real-time) and the base is destroyed.
