As of today (April 28th), the game was updated to the "Martian Express" DLC. Thus far (unlike the B&B update/DLC), all my 100+ Mods weren't effected by this, but old saves won't give you what's available on the DLC. You need to start a new game. Other than that, I have no issues with the game as of yet. The "Future Contemporary Cosmetic Pack" DLC that came out today, also works well for me.

If you're experiencing frequent crashes, especially during saves, then turn off the Steam Interface. I haven't had a single crash since I did this long ago. Also check for Conflicting, Incompatible, or Outdated Mods. Remember, Modding the game is a risk we're all taking, and updates will likely effect them.

This game is very sensitive to what else is going on in the background of your computer. To alleviate, or at least reduce sudden crashes/freezes, go to "Properties" then select "Updates" and use the drop-down menu for "Background Downloads" and select "Never Allow Background Downloads"

You may also want to open the Task Manager, and look in the Applications tab, and:

• R/Click on Survinging Mars
  
• Select Go To Process
  
• R/Click on MarsSteam.exe
  
• Set Priority to Above Normal, or High

When you exit the game things return to normal, and you have to redo the above every time when launching the game.

These are features that the vanilla game isn't recognizing, or are outright broken:

SSC Star King & Star Queen -> I'll NEVER use another Mod from these two again! They're. too "Thin Skinned" and take offense of constructive criticism. They resort to childlike tantrums. Now they no longer update their Mods, leaving their supporters hung out to dry. Their EGO's & ARROGANCE are INFLATED & UNYIELDING.

All Mods have been tested for several hours under different circumstances, and work on my computer, or I wouldn't show them. Your results may differ depending on your system specs. Please be sure to read the "Authors Description, Instructions & Notes" and glance through the "Comments Section" to see if issues similar to yours have been noted.
