Steps to reproduce in 0.50.2:

1) Start tutorial
2) Reach step "Nice work! Your base refills suit's oxygen and power. Go into the Airlock, then click on it to close the door" 
3) Be a doofus and deconstruct the airlock by holding right mouse button
4) Place airlock back
5) Enter the airlock.

OCCURS: Text stays the same, tutorial will not progress to the next step. 

EXPECTATION: Tutorial proceeds forward to "bases also have a limited supply of oxygen....".

Hey!   Oy, I've tried some attempts before at preventing players from picking up the base modules until they've finished the right tutorial step - but it got a bit too complicated, if I recall correctly. Will have to revisit to see where I left off.  

I think I did this but the issue was that the module was facing the wrong way when replaced? Since it seems to require you to enter the base not the airlock? 

I also encountered this issue. Placed the airlock the same direction it was before.
