Stuck at the end of Act 2

After putting up the towers and choosing a cure My main mission is to "Use the Gravity Sensor to leave the canyon", I put 4 alters on the towers and try to use Base Nav but despite having the cost of fuel covered it still won't let me launch.

I thought it might be because I only have 5 alters or because I was using rebellious alters that disagreed with my choice so I made another one and it still doesn't work, I also made sure all of them were on the towers (which is for some reason way buggier than usual) and it still does not work. Reloading does not fix anything.

Tech Jan has something to say to me but I can't speak to him so is that it what stalls the game? I've basically just slept through 4 days at this point with nothing new to do, I'll try a bit more and see if I'm just bugged
