That was the reason why we never released 1.05 through it, however, this time we have no other option because A2OA requires fully updated Arma 2 in order to be able to fully integrate its content.
We can not even tell atm if it is possible to manually patch first using our normal reasonably sized patch and after that enable the steam auto-update as there is no way to test it before it is fully out even for us.
