there is what seems to be a bug if not intentional but i saw no annoucement about that, after 10 days, base are going to decay state (that is normal), but now once they go in decay state there is only a 24h decay timer grace, which mean that all bases will collapse after 10days + 1. in past the grace period of decay state was matching the time before a base fall in decay if nobody connect to refresg, so was 10 days + 10 days of decay state (if nobody choose to destroy your base in decay state). this is also the case on the beta live version.(10+1, and not 10+10)
