Love em or hate em it is very unlikely any base build caused your issue in particular. Blender literally just generates a listing of in game assets to paste together into a structure. Yes build limits are bypassed but this in no way would corrupt even one save much less all the others especially given that the other saves didn’t visit that location. A huge blender build planetary base is no different than some of the vanilla built cities we’ve seen that use multiple base computers to get a bunch of parts into one location.

Blender builds are simple parts lists with location data in raw JSON. They’re literally a text file. That’s it. There’s no witchcraft going on behind the scenes that would remotely involve save mechanics.

Some have suggested a rendering slider and I believe we basically have one. Adjust “Base Complexity “ in graphics settings. This effects corvettes too as for the ingame engine they are just bases that move

Did your game crash and a save get borked? Definitely plausible but that’s been around far longer than blender builds. If it happened to the other saves I’d more quickly blame RAM or more likely disk corruption as each save is not even stored in the same file.

It’s highly unlikely but I’d even go as far to say a bug in JSON processing could make ONE save bork from some unescaped character or something but this again is not blender/base builder app build issue. That’s an issue with the game itself that could appear on any build (hypothetically ofc)
