Well, so far alpha 11 - extremely slow LUA speeds when construction is going on, but thats acceptable for an alpha.
The construction seems to leave behind quite a bit of ladders, and there seem to be no means to remove them using clear, and options to remove ladder - unlike regular ladders these options do not exist for these auto ladders…
That shouldn’t happen, what you can do is build a ladder on top of it, which extends it and turns it into a ladder you can remove…
If there doesn’t seem to be any other way, you can delete them through the console as a final option. Press Ctrl + C, click the scaffolding/ladder in question, and type “destroy”.
At the very least, this will keep your game going longer (mine’s still going after nearly three game months). Just make certain the entire structure’s finished before you attempt this, as it might spit out serious errors. Mine has a handful of recurring ones upon load, but they aren’t game-breaking.
Thought exactly the same but it needed a bit more: Select and highlight the unneeded ladder first then Ctrl C.
