I'm having issues with the burn time indication being stuck at 11min 19seconds, and the dV bar being all red. I'm in a stable 100km orbit with a shuttle, with 4 nervs 0.3+ twr and 3400+ m/s dV left in the tanks.
When I try to make any maneuver node, the burn time is stuck, and the dV bar doesn't work.
For the launch I'm using 6 boosters, a big tank, and 3 rocket engines. After tank separation, the burn times and dV bar doesn't work, even if I disable the rocket engines.
