Attachments are lost when "Send newsletter according to schedule"

I use:
Mime Mail 6.x-1.0-alpha1

And modules with Simplenews:
Simplenews 6.x-2.x-dev
Simplenews action 6.x-2.x-dev
Simplenews Content Selection 6.x-1.1
Simplenews Content Selection Views Integration 6.x-1.1
Simplenews Multiple Signup Block 6.x-1.x-dev
Simplenews on register 6.x-1.0
Simplenews Register Block 6.x-1.0
Simplenews Scheduler 6.x-1.x-dev

May be it's only my issue. Someone else has this problem?

But when sent immediately - all ОK!

What do you mean exactly with "immediately"? Sending without cron or just without scheduling?

Sending without scheduling.

Cron/without cron - nothing change, attachments are lost

I've just tested with 1.0 and both (1.x, 2.x) development branches of Simplenews with Mime Mail 6.x-1.0-alpha1 and it seems to be working just fine...

Good news! Realy scheduled messages come with attach?
Maybe it's my own trouble.

I'l try it test on blank installation of Drupal with Simplenews modules only.

Big thanks!

I have tried, but the problem remained.

attach is lost, at creation new edition of scheduled node (edition 1, edition2, and etc.):
In original it is present, but in created by scheduler - lost.
Therefore scheduled email without attach.

Yes, I use Upload module, create attachments.
