Hey, so I just experienced the same situation as this guy.
It’s my first time deploying and I had 15 TC. Deployment failed (I got an error, whereas dfx deploy works locally 
) and my cycle balance is now 3 TC…
How can I debug this without burning tonnes of cycles ? (that’s 2+ ICP tokens burnt with no benefit…).
Also, can someone reassure me that those costs are huge because it’s the first time creating the canisters (I have 4) ?
Thanks
