Need help please...

i recently added TN's M class mod along with Intrinity so that I could take my ship building to the next level (M class modules). Unfortunately, I now have an issue whenever I try to save the game it crashes. It's not the save file bloat issue because I'm not getting the message that accompanies that. I am able to load a save, I just can't create a new one as it will CTD.

I'm on XBox, and here's my load order relevant to ship building:

Ship Builder Configurator
Ship Builder Categories
Ship Building Tweaks
Ship Extension
TN's Ship Mod All In One
TN's Class M ship Building
Darkstar Astrodynamics
Matilija Aerospace
Avontech Shipyards
Intrinity Aeroworks
1 of a Kind Ships
6 Ship Engines
18 Ship Weapons
SETI
Cabot Bridge Retexture
Ship Pieces Unlocked
Better Ship Part Flips
Ship Power Allocation Fix

As mentioned, the newest two mods added that precipitated the CTD on save issue are bolded. What's odd is that issue didn't start happening right away. I was able to build the M class ship and save it, then I relocated a Darkstar terminus pad to another outpost, then the issue started. I've already tried reinstalling the game and my mods, and I think my mod order is good. I also tried disabling the two mods in question, though I'm wondering if it's an issue with the Darkstar mod instead. My question is has anyone else encountered this issue, and if so, do you have any suggestions for resolving it? I'd like to keep the two new M class mods if that's possible, but more importantly, the game is unplayable (I can't save) until I solve this.

Any help would be greatly appreciated.

Not sure if this is a problem or not, but you should download the patches for TN's mods.  There's patches for TN M Class and All in One, also for Avontech, Major. Also I have had the Avontech, Maj, Darmstadt, and a couple others. Could never seem to get them to  work together.   Found that Darkstar seemed to cause some issues. 

Cheers!
