first one worked fine second one restored the ship with no fuel/o2 and the groupings messed up and a rainbow color scheme. looks like everything is intact, but it looks like something elton john would drive on a date.
Yes, fuel and oxygen are unfortunately not restored. The colors are another game bug, but it can be fixed easily by using a repair bay or using station services to repair your ship.
It should if you have a saved template from before the deletion. Make sure that your ship has some kind of damage, or it wonโt be able to be repaired. For example by shooting a random block once with your multitool ^^
But either way itโs of course up to you if you want to repair it or not.
