Boss level bug. Level 326. Major problem.
On getting to boss at last level despite having three birds, only one is available. On firing bird the other two cards can now be used. I can not interchange any until first bird is fired.
Also looks like boss is virtually impossible to kill. Dropped Matilda egg on him and it did about 10% damage, direct hit from Terence did nothing. Maybe Boss has been made harder, that I don't mind, I do mind it taking 10+ birds to kill boss. I've screen sheets of all the above.
