Consistent crash in map editor

[Faban494]

Problem Description

Only factory planner (+flib) and all SA mods on. In editor mode. Factorio 2.0.33 factory planner 2.0.16

Crash happens consitently after a certain number of ticks both in regular, compact mode and closed mode. Crash still happens if just AFK from autosave. Crash still happens if switching to non-editor mode. In limited testing crash does not appear to happen in a new editor scenario that is just AFK.

Error message:

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