Trying to understand the Flight Results during a launch

Hi,

I'm working on a launcher, and am trying to use Stage Recovery to save some money. The first stage is a pair of SRBs, with sepratrons to push it away when decoupled. Second stage is a pair of liquid tanks with engines, also with sepratrons, and the main stage is a single 3.75 meter stage.

I need the sepratrons because without them, the separated boosters sometimes collide with the ship. But, when I use them, I get the following in the Flight Results

The amount of damage doesn't appear to be significant, since I am now getting most of the parts and cost being recovered. But it concerns me when I see that the EnergiaQuad was damaged, since that is the main engine of the main stage.

I also tried stepping the sepratrons down to 50% thrust, but that didn't help.

Is this inevitable, getting some minor damage like this?

TIA

You get the damage report any time the exhaust of an engine contacts a part.

In the current version it is trivial. In previous versions, where engine exhaust could actually heat a part, it could be more serious.

But this damage is an all or nothing thing. Either the part is destroyed, or it is not. If it is not destroyed then it won't make any difference later.

Ok, thanks.

Then I can ignore it (yay)

Now to move on the the next part of my project.

Thanks you
