Possible bug with CoL on 1.3?

[Vinil]

Hi. First time creating a thread here so let me know if I made anything wrong.

After the 1.3 KSP update I'm experiencing a strange thing happening with the Center of Lift marker on the VAB, but I wanted confirm if it's really a bug and discuss this problem with others before submitting it to bug report.

Here is what happens: as soon as I start building my craft the CoL immediately appears below the CoM. Not exactly a problem yet, but as I remember on 1.2.2 the CoL used to start on the floor and only appear after a wing was added.

As I'm adding new parts the CoM is going down but the CoL stays in the same place:

When I finally add winglets at the bottom the CoL goes down, but not as much as it should be (before the last update):

Incredibly, adding a parachute and a hetshield at the top of the craft makes the CoL move even higher:

I also noticed that loading a craft made on 1.2.2 in the VAB puts the CoL in the right place:

Probably some parts are producing drag on 1.3, and they weren't before, but the question is: it's expected? Do I need to change the design of my rockets to make them stable again? I didn't saw anything related to drag or CoL on the changelog...

 

If it helps, here's a list of my mods:

My guess is that the marker now takes into account the lift generated by non-wing parts, because before it only calculated for wings but not body lift, even though body lift was added to stock.

I agree with you, but then why the CoL stays near the pod while my craft gets bigger (before the wings were added)? I'm guessing that just a few body parts are producing drag now, but that doesn't seem right to me...

Edit: Forgot to tell... I launched a rocket similar to the one in the OP and it felt a little less stable then my commom rockets on 1.2.2 (for example, the one with the CoL marker placed at the far bottom), so maybe it's not just a change in VAB marker...
