I'm using the Landfill Everything mod with this, It seems that placing a blueprint with entities above platforms causes it to crash when being placed by bots.

Edit. Placing platforms first with bots then placing entities causes this crash. Placing platform by hand then placing entity causes crash.

The mod Platforms (1.1.7) caused a non-recoverable error.
Please report this error to the mod author.

Ran into a second error
