Found another nonrecoverable error - potentially related to blueprint sandboxes orbital sandbox? Happens several seconds after I paste a station into that sandbox for filling the bp with scaffold tiles

The mod Project Cybersyn (1.1.6) caused a non-recoverable error.
Please report this error to the mod author.

This one's a difficult one because it's being caused by space exploration's modding interface. I'm not sure I understand your description of how the error occurred. Do you mind re-explaining what you did that caused this error?
