no, no more problems thanks. in future if i only report crashes which i can re create would that be more useful?

apologies for late reply, it took me a while to get memtest working as my knowledge of computers is very poor... i left it running while at work today for a total of 10 passes and it showed no problems. however i also found out that my nvidia drivers were out of date so it could have been that?

loaded up the game again and it happened again... loaded up a 3rd time and could play as normal.

not sure what was needed so i copied what someone else had done...

playing on latest version - latest 0.16 experimental on steam (0.16.x) no mods. i had just loaded up a save, was walking around holding a blueprint.

let me know if anything else is needed, hope this is useful.
