Crash loading mod

[amoss]

Problem Description

This looks like the same issue as in https://github.com/ClaudeMetz/FactoryPlanner/issues/358 but it is present in the latest version (2.0.2). Doesn't require a save - just trying to activate the mod and restart Factorio triggers it.

7.814 Error AppManagerStates.cpp:1631: The mod Factory Planner (2.0.2) caused a non-recoverable error.
Please report this error to the mod author.

I've got some of the Py mod enabled as well. Will attach a log for reference.

}

Reproduction

1. Start Factorio
2. Enable Factory Planner
3. Crash happens! (not quite the template but close :) )

Hi, thanks for the report. This is a different error than #358 actually. The crash you got can however only happen when loading a save, which the log confirms. I tried it by starting a new game with your modset, which works fine.

Do you happen to still have the save this occurred with?
