Bug with ksp1.6 dv tools

[bitzoid]

I just upgraded to 1.6 (and was I surprised to find the dv tools!) and noticed that it's calculation was off from mine. I boiled it down to decouplers with enabled crossfeeds and several engines. But I am not sure if it can be done without decouplers.

How to reproduce:

1. Place a Rockomax X200-32 fuel tank. Empty the oxigen (I *think* this is not strictly necessary).
2. Put a TD-25 Decoupler below it.
3. Enable the crossfeed of said decoupler
4. Put another X200-32 fuel tank below and empty its oxigen as well.
5. Put a TVR-200L Stack Bi-Adapter (not necessary but it's the easiest way to show the issue).
6. Attach a single Nerv to one side of the bi-adapter. The burntime is correctly computed as 1883s.
7. Attach a second Nerv to the other side of the bi-adapter. Now the burntime jumps to 471s. Correct would be 942s. (The dv is equally wrong)

Best.

 

P.S.: Is this the correct place for bug reports, anyway?

I posted it to the bug-tracker. I'm pretty sure it is a flat-out bug.

If you need a quick workaround: Disabling the staging for the decoupler seem to fix it but you have to use an action group or the part action menu to fire the decoupler.

Yes, I originally had the problem with structural pylons that I wasn't even going to decouple (or stage for that matter) -- I'm currently into builting Federation-style engine-nacelles. It still manifested there, but I opted for an MWE for the bug report, with the downside that it only showed in the MWE when activating the staging.
