hi i"m have a problem with advanced rocketry.It's start when i wanted to go on moon and when i was teleported to another dimension i can't leave my rocket and i not see moon just only stars.I restart my game and it worked, but when i wanted go to earth ,i'm press a lunch but game teleport me under bedrock.I can't find my rocket and grave.

You are on the moon, the biomes just get messed up, it been a reoccurring bug. It looks like it's been fixed in 6.0 (for a couple reasons). As for the grave, go into spectator mode and look around in the ground above the the spot it says you died. With graves of you died where it cant put a grave it will try putting it higher up in the nearest air space. If that fails there is a command to restore the inventory, something like tmg_restore.... that's the start of it and can use tab complete to get the rest of it
