If you're creating the raw transaction and don't provide a change address, doesn't that mean you just spent the change in miner fees? In other words, if you have two input transactions of 1BTC each, and the amount you're spending is 1.01BTC, without a change address, 0.99BTC becomes transaction fee.
That is correct.
Thanks for the confirmation. When I read that OP "fixed" the problem by just removing the change address I was like, "who messes around with multi-sig stuff and raw transactions without even understanding the basics?"
