I too ordered a backpack in September and received in December, my idea was to build my next armor and become approved as HWT then later move on to a TD.
I realise the CRL's are currently changing BUT we had a heads up about EIB and Centurion changes 6 months prior to the CRL being changed a while back, members where encouraged to build to the new changes even though they had not come in, SO why did this not happen with the backpack change?.
Hopefully a research of the character may find one not wearing a backpack and the CRL can be changed again
I would just like to say the comment "But if you had spent more time researching the actual character than the loose description of it you should have realised that a sandtrooper pack is just wrong" I find contradictory. We are told to build to the CRL, we do the research, we build and changes are made to the CRL, who's fault is that, it was stated clearly in the CRL as Markus pointed out. Who would build to a character and not go by the CRL, really!
