Surviving Mars - Holes / transparency in terrain tiles

Holes / transparency in terrain tiles

What is your game version?
227,923

Please explain your issue is in as much detail as possible.
When zooming out to the planet map then back in, there are large holes of missing terrain, where you can see the "skybox" far away beneath. I am using dual Nvidia GTX 560 Ti video cards. It does not seem sensitive to any video settings changes I can find - it occurs at all levels of terrain quality though more frequently at higher quality settings.

Can you replicate the issue?
Yes, very consistently. Just zoom in and out, and after a few iterations (2-3) terrain holes start appearing.

I can attest that this happens also with a few other notes.

I have noticed that sometimes it will draw the wrong terrain where a hole in the terrain may appear. ie: at one point it appears as if it was a concrete rich area (no icon) but after a few zoom in's it reverted to default red terrain.


Could be linked to long running time of game session.
Exiting to Menu and reloading game seems to resolve in the short term
It happens more commonly when zoomed out. closer in zooms seem to not be affected. I have seen it on the map level as well. It also appears to happen to dome terrain (pic attached). (Memory issue?)
Locations appear random. Seem to change passing over regions. Once it was the terrain under a ramp to my rocket, later it was a tile or two below

I also am using SLI Nvidia's. neither are dedicated to Physx. two monitors, off of one card.
My graphics settings in game are Max/Ultra
