Happened to me as well - not sure if it's related to defined "heat resistance" values or due to its stage - even after opening the heat shield fully it still registers its stage as "moving" in the parts UI

Just to echo this, though it might be a separate bug - extendable heat shield is absolutely useless while entering Eve, pretty much self-destructing shortly after falling below 90k km. Not sure if it's related to defined "heat resistance" values or due to its stage - even after opening the heat shield fully it still registers its stage as "moving".

Happened to me a few times, quicksaved before decoupling supporting boosters; trajectory disappears after staging. Decoupled boosters that got the debris class after staging still had a trajectory, worth to mention that these were connected to the main booster with a fuel line. Managed to workaround it by moving boosters decouple action to the next stage. What's more, after quicksaving after trajectory disappeared and loading this save, the vehicle loses all its speed and just free falls vertically.
