I'm running into this as well on the 5 Oct 15 main branch build.

it's solved in first beta

I confirm this bug.

Let me refer to Issue 0000573 reported by DHLF:

Reason: Critical error:
Out of memory when requesting 22369620 at C:\EnforceNG\Enforce SDK2.1\engine\src\Render\enf_texture.cpp(1385)

Same error in C:\EnforceNG\Enforce SDK2.1\engine\src\Render\enf_texture.cpp(1385) .

All tasks are reachable, but several require going inside the caves to complete.

I noticed it also resets if you hit ESC at any time.

This occurs on Windows 8 64-bit as well, in both the test version and the current steam version.

The update (4 may 2015) killed this bug.
Previous save files for the above mentioned scenario are loading without problems
Thanks a lot, developers!!

I agree, I would be a good thing to be able to recover the resources (when we start needing resources) for printed objects. It would be a waste of time to not be able to re-purpose those base materials.

I am pretty much able to 100% crash on my current save if I try and drop anything out of my inventory or from a crate. Very annoying.

Edit....
Im on the Test build btw.
Been playing more and was able to locate all 3 supply drops and set everything up at the crash site. It seems that if we don't fill our inventories we wont get crashes. I will keep playing around and see.

After each crash was handled by OS, I started again.

Sadly buildings of a size of 5x5 are not possible to build yet due to overflow of something. Try to build 4x5 maximum. Also using large tiles(2x2) instead of 4 single tiles may be helpful.
Those 5x5 means putting 5 base platforms on the ground.

Restarted S1 prototype Lyot
Stand up from the ground, saved immediately and tried to reload this savegame.
Rover circled-freezed-circled again,
Press any key message appeared and.. crash :(
