Conquest S2 Boss unkillable

Why this game begin to be a stupid joke.
Its a 1+b game . If they cant fix those bugs, shut it down,fix it,give us crystals back for the energy that we spend and start again.
How is that posible after 14h the game is the same. S2 Jabba cant be kill. I use for S1 bosses,12h ago , Jabba vs the pig and cls old school for the rancoor. Wookies give me the win against bh in S2 mini boss, but the last one, Jabba, nothing works
