Fuel Lines not Working

[SelectHalfling0]

I have built asparagus rockets many times so placing fuel lines is nothing new to me. Today, when I tried to launch a newly created rocket, the fuel lines were not connected (even though they were in the VAB). I reverted to the VAB and they were not connected. I rebuilt the launcher and the same thing happened. I then reloaded the game (2 times) and stopped using open-gl, yet none of those fixed it. I went to a ship that had fuel lines previously attached and launched it, and the ship had fuel lines attached. None of this makes any sense to me.

I use KSP 32x .90 with:

Kerbal Alarm Clock

VOID

Chatterer

Distant Object Enhancement

Raster Prop Monitor

Probably had mirror attach mode active instead of radial, when fitting parts press R to switch

I checked that too, and I was in radial.

But: I verified the integrity of my cache (through steam) and that seems to have fixed the problem.

Thanks for the suggestion though!
