Efficient Traps buff(time halved)

[Nikosis]

For the past week the efficient traps buff is only giving half the time , ie. 9 hours instead of 18 on friends building.
Is this a bug , or has BB minimised the time it lasts. Please BB check and tell us.

Works perfectly for me; 18h when placed by a friend
