As title suggests, for some reason I'll randomly have the shaft to go up from a surface be deleted. It's not biters up above attacking anything, and I've yet to catch exactly when it'll happen. I just know that sometimes when the shaft entrance is off screen it'll be deleted with no signs of what causes it. I've noticed it from above and below ground, even getting trapped down there and requiring a reload once.

Ores still don't seem to be generating below level 1. This bug is current as of today when I was testing it. Speaking of ores, it seems that depleting a certain spot on a patch (Like around the edges when you are only using burner drills) causes that same spot to generate empty on the subsurface below if you mine everything out before revealing the sub surface. Also not sure if intended or not but I did not seem to find a stone patch underground either .Granted with how much stone you get from the digging it's not a huge issue, but also seems kind of weird. The surface stone patch generated pretty light, which I assume was due to the same thing that causes the other resources to be generated light, but without the benefit of subsurface patches to exploit.

Do you use other mods?

Stone is indeed not generated in subsurfaces, you found the reason why.
Ores on the planet's surface have only 10% richness compared to vanilla, but the patches below have like 100% with a decreasing patch size.

This "disappearing entrance" thing has been happening to me as well, and is rather annoying, the main thing i notice, is that it's happening in the order i dig them, so, are the entrances treated like ghosts and timing out or something?

Love the idea of this mod, keep up the good work :)

no, no ghost or timing out.
What about other mods?

oh, sorry, I didn't notice you responded.
no ghost, no timeout, it just suddenly wasn't there.
I had a few other mods, mostly Lignumis, Cerys and Maraxsis,
I stopped using this mod because it's very hard to test for this bug, it was mostly happening in long games.

I would go off to another planet, and obsess over my Aquilo base for a while, and return, and.. entrance to the Nauvis subsurface was gone.
the only clue I had, they would vanish in the order I placed them, like they were on a 50-100h timer, or something,
like when I noticed the Nauvis subsurface 1 entrance went missing, I re made it, tested everything was back, and, the subsurface 2 entrance vanished
I dug it immediately, only for the subsurface 3 entrance to vanish.

oh, and nothing vanished while I was looking at it, I expected my subsurface 3 entrance to vanish, so I was camping it.
But it didn't, so then when I moved my attention somewhere else, and came back 10 minutes later, and THEN it just wasn't there, like it had never been there in the first place.

I'm also experiencing this bug. However I haven't even left Nauvis. I have dug two entrances so far, and the second one has disappeared twice seemingly randomly. have Cerys and Maraxsis installed, along with a variety of other mods, but my modpack is relatively light in my opinion. We are only 7 hours into this run.

Are there any other objects that are deleted?
The entrance is set to be indestructible and 100% resistant. There must be some mod influence.

No other objects were deleted that I noticed. My best guess is that something in Maraxsis is going on, since that mod has a surface you can enter by going to these trench areas. And I assume there is some code running in it that is interacting with subsurface. I'm not super familiar with developing mods for Factorio yet otherwise I'd try to do some sort of logging

It's been happening to Me too, i have a save file Right Before it happens, it's triggered by the next 2 left clicks, anywhere if you want i can send you the save file so you can see the exact circumstance and mods i'm using

Yes please send me the save file, without DLC mods

save file
right at cave entrance, 2 left clicks anywhere and entrance dissappears, at first i thought it was the dialog box but turns out clicks anywhere triggers it
If one enters the cave and clicks while in entering animation it stops the removal of cave entrance.
PS post on wrong thread earlier sorry

I have another save where after 3 left clicks it does it, it's something to do with the number of clicks? very strange?

some kind of counter thing

REMOVED Maraxsis and then it didn't happen, so that seems confirmed =)
