The decay rate has dramatically increased since the last update, after 4-5 days I have some towers down to less than 50% HP, when beforehand I could go 8-9 days without repairing. I’m not sure if this is intentional or not but I hope it isn’t.
PS: Yes, I have at least 2 other connecting buildings to each tower.
I also have experienced a more uneven decay since patch. I have repaired every 2 days at most since and have had structure pieces as low as the 60’s in percentage. its not uncommon for new code to change how old code interacts or functions. worth looking into.
