Message blast when 2 or more trainers send at the same time

Bugs
#1

if 2 or more trainers send a message blast, student gets only one of them

  1. if 2 trainers send: Student get the last one
  2. if trainers send at the same time: I’m not sure about the queue but again student gets only one of them.
