[[Minimum KSP version - 1.11] Kerbal Attachment System (KAS) v1.12]

I've spent hours researching an 'interesting' problem where the CC-R2 connector only shows up in Sandbox mode.

 

If you unlocked the CC-R2 from the Tech tree, could you please tell me which node it's in?  I can't get this part into my career game, or find it in the tech tree, regardless of whether I start a new career and whether I delete all mods besides KIS/KAS

[[1.2] DSD Mobile Labs]

I'm having what appears to be a bad interaction between DSD and one of my other mods.

 

The stock mobile lab (the one with MPL in the name) is reduced to one seat (crew capacity=1) with DSD installed, however the lab cannot be used for anything because it requires two crew members.  Starting the lab shows the 'Not Enough Crew (1/2)' error.  It is impossible to move any experiment data into the lab (the lab icon is shown but the text under it has three hyphens "---".  It doesn't help if the total number of kerbals on the ship is equal to two.

 

If I can figure out which other mod was causing this, I'll mention it here.  I have a few dozen installed O.o

Update:  It is the SETI Rebalance Mod
