Welcome back to The King Community.
Time boosters are currently provided through test groups and in these groups players are randomly selected.
Whenever king development crew wants to introduce a new feature, they try it first on a number of players that are randomly chosen, to check if everything is alright.
A/B testing is very common practice in the IT industry and it is put in place for technical reasons. king need to know if the feature can be supported before releasing it to the whole world.
Here's an article on Wikipedia about A/B testing, which might spread some light on this practice and why king do this: https://en.wikipedia.org/wiki/A/B_testing.
Luckily this is not a problem, its completely normal and You must state your statement here.
Promotion allocation is random, and so king unable to send or re-send/reset the active promotions for specific players. Sorry for the inconvenience.
