Woah thank you a lot for the time you've invested in the game. First, let me tell it's a really nice comment :) I intend to work on the game a little bit after the Jam, mostly fixing the UI so there's less clicks.
For the first bug you mention I see what you mean. It happens once when I've quickly tested the game before releasing it. I wasn't able to reproduce it so I was confused when it happened. Now it makes muuuch more sense. With what you said I'll be able to fix it quite easily !
I've just tested the second bug you've mentioned. I'm not entirely sure how to fix it yet, but I think it's related to the first bug. It's certainly a variable that's not resetting properly.
You're absolutely right about the repair's color. Since in the "Phase 2" locked actions are red, unusable actions should also be red to prevent confusion.
Again, thank you a loooot for the time you've invested in my game and this huge feedback. It means a lot for me since it was my first Jam and my first game !
