MK3 shuttle can't make it to space

[Jedi Kerbal]

I've had a MK-3 shuttle powered by 4 Whiplash Engines and 2 Tory Nuclear Ramjets to get to orbit and a Terrier and RCS for on-orbit maneuvering.  With a little care it could make it to orbit carrying a half-full Rockomax 64 and have some delta-V left for other ops and then liquid fuel for a little atmospheric flying to land.

A few days ago, I let CKAN update some mods.  Since then, I can't get above 23k altitude and 11.5m/s, even empty.

Thoughts?

Thanks

Welcome to the forum, @Jedi Kerbal!!

By any chance could the mod for the nuclear ramjets have updated? That could have broken your shuttle.

In that case you could try removing the part and then replacing it. For some reason it works, at least sometimes.

If that doesn't work, try spamming boosters on the side. It'll get into orbit eventually
