When an account is created and abandoned for a long time, so that the initial steam turbine is decommissioned, the account is blocked forever.

this is kind of a niche issue.
Suggested solution : After some time of inactivity, the simulation for an account is paused so that no money is earned or lost, and no progression whatsoever. When the player logs in again, the simulation for the account is resumed.
