1.5 Rapier Bug, Warning StageInfo: Simulation Time Exceeded

[Jasper]

I'm having this weird thing where, once i take a rapier above the limits of it's airbreathing mode,

So here's what happens, Fly up to the point where airbreathing fails, switch with action group to closed cycle.

then after reaching decent altitude i switch em back to airbreathing to 'turn them off' (toggle action group)

But in airbreathing mode the debug console spams with these "Warning Staginfo: Simulation time exceeded" warnings

and the game just takes a dip in fps. Keeps looping as well as long as the airbreathing is active.

First i thought it was mods, but i built a replica in just stock with the same results

I know i could just turn the engines off, but i'm stubborn. Took me a while to find the culprit

Anyone care to enlighten me as to why its spamming so much?

I am having the same issue, but also with modded engines. It would be best to disable the stock delta-v calculations, but I do not know how to do this.
