I'm starting a TFMG map, and got this error. Factorio loads fine, it's when the map starts. It might be because you don't have a player character when the mod starts, just a platform in space. I'm hoping it's something you can handle on your end. I won't have logistics (or a player character) for a while, so I can add IL back in later.

The mod Logistics Insights (1.0.14) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event logistics-insights::on_player_created (ID 32)
Unknown sprite "technology/logistic-system"
stack traceback:

Interesting mod. The problem simply is that the mod removes the standard sprite called "technology/logistic-system", which I use in the Network window to show a network.

I'll post a fix tomorrow. Cheers.

Please check out 1.0.15, which should deal with this more gracefully. Thanks!

Thanks for the update, but got a new one:

The mod Factory Planner (2.0.46) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event factoryplanner::on_configuration_changed
factoryplanner/backend/handlers/defaults.lua:149: attempt to index field 'proto' (a nil value)
stack traceback:

That’s Factory Planner though, not sure I can help there?

FWIW, I only get this error message when both LI and Factory Planner are active. I've also notified the Factory Planner owner.

I've tried it, and I can see that there is a problem in FactorySearch's code when it tries to do something complicated with the default prototypes. In my tests, it fails with TFMG, whether LI is there or not though; I don't think LI has anything to do with it.

Do you find that it works when LI is not enabled?

Like you, I'm now only getting the error when Factory Planner is active, regardless of LI's presence (and I'm assuming you meant Factory Planner, and not Factory Search??). I ran TFMG from the start with Factory Planner active. FP wasn't even on my radar until I reactivated LI after your update, which is when I started getting that error from FP. Now, however, I'm getting the FP error message regardless of LI, so who even knows.

Looking at the code, my best guess is that there has been a TFMG or Factory Planner update that broke something. Best of luck with it :)
