Got a crash when running with a lot of mods.

Problem Description

I tried to start a new game with a lot of mods but got this crash, and error message:

The mod Factory Planner (2.0.16) caused a non-recoverable error.
Please report this error to the mod author.

I think this is a duplicate of this issue, likely caused by Cerys (or there might be another mod using this newly added Factorio property, that Cerys was first to implement, according to them on the mod portal discussion page)
