Advanced Construction training won't go past Install thrusters

[ArnoldKerman]

Hi, all.

I place the four RV-105 thrusters on the tiny tank, using 4-way symmetry, but Wernher won't let me click Next.  I don't know why. How do I make Wernher happy?

Thank you.

You have to read through the long text and make sure everything mentioned there is done.  I can't quite remember the other thing(s) you need to do at that step.  Maybe you also add batteries at this step, or fill the fuel (but not the monopropellant) tanks back to 100%,  or turn off the CoM indicator.

You don't have to do the tutorials if they get too frustrating.
