I loged in at 1day-23hrs on the game "Population boom 6-1" on Sunday, May 8th. Traded cards and when I clicked on APPLY was told not this player's turn. So be it. However, I had traded in a set of cards. When my next turn came about, POOF, no bonus. Not only did I not get the turn. My cards were gone! Any reasonable explaination?

I guess you simply got skipped in a board where keeping armies in reserve is not allowed. Hard to recover from that, but I guess that's the rule.
