Ok, I was going to avoid this sub until I beat the game, but I am so lost that I've gone to extremes to find a solution.

I am trying to make it into the ash twin core.

My computer log shows that I've discovered everything, no little orange stars to show something incomplete, the only thing undiscovered is the ash twin project, which I do not know where to go from here.

Is there any clue in my ship log I am supposed to look back on that can help?

Before you say anything here are some things I've observed about the ash twin:

The core seems not to orbit with the rest of the planet from the inside. I know this because I sat in the weird viewing portal thing for the ash twin

Another thing I noticed is a portal or something opens on the inside when the sun is exploding. I'm not sure if this is related to the big towers on ash twin glowing during the same time

I've noticed that the tower things possibly reach the core also

And one thing I'm not sure is related is a blackhole opened at the ruins on giants deep during the sun explosion. It took me right back to ash twin when I went inside

I've also noticed the vessel in dark bramble needs a warpcore

I'm so lost I literally went to ember twin, followed the underground city, made it to the high energy lab, grabbed a warp core, went to dark bramble, died a bunch from the fish, repeat all these steps over and over until I reached the vessel, attempt to connect the core, says core does not fit.

I am desperate. Please help (preferably without spoilers)
