Does solid rocket engines not produce enough heat to destroy parts underneath it?

[Sokar408]

I haven't played in a while, but am current doing another playthrough. However my usual "stack solid rocket engines on-top of each other" doesn't seem to work anymore. Is this a problem with some of the mods I'm using, or is this done on purpose on behave of the devs?

The last time I tried it, it took about half the burn time of the second tank to destroy the first. During that time, the booster had maybe half its normal output. Love or hate it, it is an intentional "fix" by the devs.

I don't have a problem with it being a fix, I just wanted to make sure that it wasn't one of my mods that was messing with the thermal system.
