Whenever you select In sandbox, I immediately crash when I go to select a building that requires a single material after already having a building that requires two materials. This has been happening since the patch on 10/10, and is happening on the patch on 10/12 as well.
I've tried multiple saves and new games, as well as a full reinstall.
Steps to Reproduce
Enable sandbox, click build and select a building that requires two materials, such as high pressure vent or steam turbine. Then select something that requires one, such as insulated tile. Immediate crash.
This issue has been fixed in either a future version or updated in a previous version.
