Brief description of your issue (aka the problem)

Centrifuges from SSPX (and many inflateable parts not just in SSPX, really) cause explosions when craft is constructed.

Operating system

Windows 10/11 (upgraded, still having issue)

KSP version

1.12.5

Version of addon

4.0.99.33-prerelease

Steps to reproduce the behavior or issue

Make a vessel, I managed to reproduce with just a centrifuge, some command modules, and launch clamps.

Expected behavior

For the craft to build radially from the docking port

Actual behavior

Well, The centrifuge is fine but the parts connecting it almost always above it then see a penny on the ground and throw themselves into it trying to get it. They throw themselves a little too hard and instead of getting the penny they eat dirt explosively. The vehicle is now decapitated and is just some engines hanging out.

If you turn on unbreakable joints it turns into a super merry-go-round where the centrifuge swings its self wildly in a circle around the vehicle.

Environment

Full mods list from CKAN. Worth mentioning that the version of Simple Construction here is arbitrary.
I overwrote it with your curseforge version. 
(You can copy and paste this into a CKAN file if you wish and it should work):

Log files

KSP.log UPDATE: added MM config: ModuleManager.ConfigCache.txt

Screenshots

From start to finish, here is what happens: https://imgur.com/a/Itg2fTl

Additional context

Happens across all versions of Launchpad.dll (EPL and SCON versions).

How did you download and install this?

CurseForge (download and manual installation)

Added MM configcache to logs section

@StormCircuit well there are three basic levels of log errors (you probably know this) for KSP - from least to worst - [WRN, [ERR, and [EXC

your log is showing 214 EXC that may or may not be related to this issue.

Query: does this happen in space where there is no gravity? (If I find the time I will test as well)

EXC(eption)

examples of EXC:

NOTE: just because a certain mod creates a EXCeption log entry doesn't make it the culprit - hence why I say 'symptom or cause'

CommunityFixes,Scatterer, kOS, Parallax, B9PartSwitch, and Janitor's Closet seem to either be the symptom or cause of the 214 EXC in the log.
