Construct FabriBot button invisible

[Former user]

Build b37b. Constructed my first Factory. The button to construct a Fabribot is invisible. The progress bar is there, as is the "increase max" button. The roll-over for the button works as expected. Clicking where I think the button should be does nothing.

I can only build FabriBots by using the Automated slider, which seems to work fine.

Fixed this in b38a.

For some reason the button was flagged as invisible when it shouldn't be. Jumping to a new sector and back again fixes it, but isn't a great solution. I wasn't able to re-create what caused it so instead I've added a check for whenever the player clicks the 'FACT' tab to check if the button should be there, and if it should, sets it to appear.
