[GLITCH] Troop lab timer finished and i dont know how.

My Lab had about 2 hours left and i gemmed it becuase i wanted the builder and saw that my lava hound still had 1 day 20 hours left to finish. I went to my builder base to collect my resources and when i went back it said lava hound upgraded to level 3 or something like that and i looked at my books and gems and i definitely did not use any gems and i still had my book of fighting and book of everything. I think it was a glitch but hey im not complaining.
