It will be in the next update!
Hey, definitively not a rude question. I'm afraid I'm very bad at estimates of this. I'll mostly be occupied with other work in the coming period. This is fun work, but it does mean that I will have limited time to work on this game.
And I still have a considerate backlog for the next update. I would say it should take two weeks to a month, but it may well take longer. I'm considering just releasing the Bolt and related buildings separate from the rest of the update.
