Kyva told me to go to the lab but the lab option can't be clicked.
Two options, one's safer though. First option is just restart and skip through all the old text. Game's not that long yet and there's no gameplay/grind to get through, so this isn't so bad, and is the for-sure fix assuming this was an old-saves issue and not just an issue for everybody.
The second option: After looking at the .rpy files and enabling console via UnRen, I solved the issue for myself by entering "LabOpened = True" in the console. But any time you use the console to mess around with variables, there's a chance you cause some issue down the road with your save. So keep that in mind. (Edit: For the record I think the odds of this happening in this case are really, really minimal. But just so the warning's out there, felt I should mention it.)
