Expected behavior
The transaction should be balanced

Environment and software version (please complete the following information):

• OS: Ubuntu 22
• PyCardano Version: custom branch

Additional context
Minimum breaking example to be isolated

Looks like I need to setup a wallet and submit some transactions onchain to be able to reproduce it. Alternatively, is it possible to use this newly added feature to capture the state of txbuilder for debugging?

[cffls]

Does this still occur in the latest version or may I close it?
