Rover stuck inside core (like the terrain of the core, its stuck inside the terrain)

[R4-D10]

ok so SPOILERS PEOPLE. ok now then: my rover (medium variant) somehow got stuck at the core of sylva and by stuck i mean STUCK i had also brought my trailer which had all my batteries on it plus carbon for the generator attached to the rover. so basically: the trailer was stuck inside the core so i was trying to get my rover into to core to retrieve the trailer and of course that fails as my rover keeps failing to enter the core and just gets sucked to the big central pink pillars (and here i have a brain fart so i cant remember exactly what happened) but uh something something rover bugs out, i can see it on my map and it seems to be near the trailer but i cant see it, its either bugged inside the terrain or somehow invisible and just so you know i was stupid enough to not realise you could duplicate a save and due to autosaving with the rover seat its sorta stuck there, any ideas on how to get it out or will i just have to make a new one?

you can dig up on the top of one pillar or if you already have a path going down you can prescisly jump on to it.
