buy a few silver packs and you’ll see

This is kind of ridiculous now. :)

for once a bug that kind of works in players favor 

Looks like they nerfed it, only getting 1 energy instead of 10.

they "fix" it in the worst possible way  , by not fixing it and just  removing the  0 from 10 , instead of actually making an effort to calculate a fair drop and balanced rate .
And to support my claim they also  modified the gold box , from 10 to 5 ..like .. why !???

I worry that they are not playtesting any of these changes.

they are not known for playing their game, bad coding skills + not playing your own game = ....

Again we agree, it is nice to sometimes get a nice bonus of 10 energy more so then most of the time 1. Losing the "Oh nice!" effect completely!
