wallet.SendWaitTransaction deploys the contract instead of sending the transaction

[SsNiPeR1]

When I try to send a transaction using wallet.SendWaitTransaction, the contract gets deployed. When I do it second time, it tries to re-deploy the contract, which results in "Something happened but we don't understand what.", but no coins get actually sent for some reason.

Hi, it looks like not enough coins on balance to send, and mode 3 is used (default). Try to increase balance on the wallet before sending, or use mode 130 (128+2) to send all remaining balance.
