Decay Timer Maxing Out

Game mode: [Online] Official PVE
Problem: [Maybe BUG]
Region: [EU]

For some reason I can’t open topic in Support so I am writing here.

So basically around the end of the month I am planing a short trip and I won’t be home for about a week. I heard that max decay timer is actually 360h but I seem to not be able to move away from 144h. My base is not exactly small and is fully made out of T2 material. How can I reach 360h ?

Steps on how to reproduce issue:

  1. Build
  2. Upgrade
  3. Build
  4. Still no 360h

144h is the maximum right now.
