Incorrect sidechain deposit payout amounts

[MurrMcK]

Using DriveNet 7, making a 10 BTC deposit to the sidechain caused me to receive 993.43923620 BTC on the sidechain (classified as mined). This is slightly below the 1 031.42929440 BTC that was classified as ¨Watch-only" on the main chain at the time.

There were similar results for the 10 BTC and 5 BTC deposits i made shortly afterwards (~1013 and ~1028 BTC received respectively). After that, however, a 2 BTC deposit successfully gave me 1.99981960 BTC on the sidechain, before the next 2 BTC deposit gave ~1037 BTC.

@MurrMcK Did you use a modified version of the deposit code or the "official" binary? At least one (and perhaps all?) of the incorrectly processed deposits seem to use segwit transactions (which at least one person modified the code to do that I know) while our code does not.

[MurrMcK]

@CryptAxe I did not change any code at all. I tested some deposits with DriveNet-8 though, and did not run into any problems.

[CryptAxe]

@MurrMcK thank you! So you've had a deposit actually go through correctly for you now?

@CryptAxe Yes. I made one deposit by itself and I got the correct amount on the sidechain. Then I also tried 2 deposits in the same block and both of those also came through correctly. So DriveNet-8 has had no problems with deposits for me.

Leaving this open until I actually figure out exactly what went wrong but that is good.
