Sorry, I just made this new account for uploading this report and unable to share any screenshot yet (I just tried…). After facing this problem I spent 5 days to remove everything not directly connected to ground, and built something new with stability loss set to 5 for all foundations and planning to use some support beam to minimize calculation thanks to individual stability data for each block. But it is still just a basement of rectangular sections. Hopefully I can make something out of it before 1 dimension calculation also crashes and show the results here later on. Cheers

(So just had to spend 1 hour free chatting. Screenshot at below, took me 7 min to start with 100k blocks)
