I used the replace feature to replace my old spaceship design to a new one and this caused a crash, looking at the logs it seems to be from a Turbo underground belt ghost enitity not being replaced correctly.
It was reproducable after loading the last autosave, trying to replace the spaceship with the new blueprint produced the same crash.
I opened the last save, opened my space platform I wanted to replace, opened the blueprint menu and selected the blueprint I wanted to change the spaceship to, used the replace feature (ctrl + shift + left click) and then the game crashed and I got the below crash log.
I kept playing for a bit but seems I can still reproduce the crash, I have attached a save where I can reproduce it, the blueprint and the crash logs.
Not a big issue as I can just delete everything on the spaceplatform and then place the blueprint but still weird.
Factorio crashed. Generating symbolized stacktrace, please wait ...
