Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
As a workaround you cant type /choose move 1, pass or /choose pass, move 1 in the chat. That should work.
The Client seems to think that the fainted blissey (which the client identifies with 0HP) is still alive and tries to send a move option, which obviously does not work D:
I found my dice set, and even though they were a little dusty I got some results.
I checked:
Heracross-Mega Intrepid Sword (2)
Heracross-Mega Defiant (2)
Heracross-Mega Defiant // Intrepid Sword
(all choice banded)
The Defiant(2) Teams gets outperformed.
Intrepid Sword(2) and Defiant//Intrepid...
Is your team good enough or are you actually unlucky? If you dare, post it and I will find out the true potential
