Ok, so me and my brother rebuild our base section by section. We saved it like every 10 minutes and copied the save to a different folder, after the base was finished we started to load each save to see what one crashes and what we adding from good save to bad save. P. S. we used no Tvs, water, minning, stuff, only used walls, floors, windows and door locks ect. this crash seems to happen when you save and the save is sent to the other player, you can see the part count. it seems after the part count hits 400 thats when the saves will not load and you get the above errors. Dram, any insight to this problem? even if nobody knows just a look at it would be nice. we only play because we love building things and we can not progress anymore. Thank you for looking :)
