1 tDusk missing from wallet balance

[Rigorously]

After testing the blockgenerator, 1 tDusk is missing from my wallet balance.

stop

After waiting a few hours I exited the console with CTRL + C because the console would not return control (see #2). Coincidentally the test monitor was stuck at height 13903.

I restarted my node to check whether I could reproduce the error. Unfortunately I did not manage to sync, but I also noticed 1 tDUSK is missing.

We found out what caused it - it seemed to be a rounding error, found in wallet.go, line 363. A fix will be pushed shortly.

I used the faucet and synced. Now I have 19.99999800 tDusk. 0 spends and 4 receives.

Oh I see. Every time I execute bid or stake I get one receive and 0.00000100 tDusk is deducted. Is that a fee, like gas for Ethereum?
