Here is how my nights went, to clear things up.
Start of game: My action costs 20 coins, and I start at 50. That's two actions, with 10 coins left over.
N1: Notme's death gave me tens coins, bringing me to 60. Not taking into account the economy, That is exactly 3 actions with no coins left over. Economy is at actions cost -3, so using my actions (for which I was blocked) cost me 17 coins.
60-17=43.
N2: Economy is now at actions cost -6. That means my action costs 14 coins. I used my action again, bringing me to 29. Without notme's 10 coins, I would be at 19, which is not necessarily enough for an action, considering the cost of 20 coins. I think I maybe realize what you are saying now, but frankly im still not sure.
N3: I used my action again, and since economy was still at actions cost -6, I should have 15 coins rn.
The "its fine bit" strikes me as kinda condescending, but you are right I forgot to take into account the hypothetical third action is not neccesarily 20 coins.
So maybe I do have an action left. (stay tuned im waiting on host confirmation)
