This mod looks great. Thank you for working on it.

Sorry about that, should be a quick fix... presumably the inventory was empty when it died?

Reproducing the issue, it looks like it wasn't my Spidertron that died, but instead a Companion Drone. Don't know why that is considered a Spidertron, though I see other discussions on compatibility. I tried putting some items in their inventory and it still causes the error.

[ignore]

Oh that’s helpful, thank you! I’ll need to disable corpses for them entirely.

Btw for the time being you can disable corpses in the startup settings. (It will require a game restart but won’t change anything in your map except delete existing corpses).

Oh this was a lot more serious than I thought: any spidertron dying triggers this crash, but I didn't notice it because it specifically doesn't happen when using the mod development debugger. It is fixed now in 1.4.4.

The reason companion drones dying triggered it is because internally they are actually spidertrons :) With this mod they also leave a spidertron corpse which isn't ideal, so I'll probably remove/change that in a future update.

Hi I have a similar problem:

The mod Spidertron Enhancements (1.0.0) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event SpidertronEnhancements::on_entity_died (ID 4)
SpidertronEnhancements/spill_on_death.lua:24: attempt to index field 'trash' (a nil value)

Disableing corpses did not solve the problem

Try updating the mod 😁
Your version is extremely out of date!

https://mods.factorio.com/mod/SpidertronEnhancements/changelog Look at all these changes you’re missing out on!

But your newer versions are only available for 1.1

Oh right, well unfortunately I’m not able to support 2 versions of the game at once, especially this long after the release of 1.1. If it keeps on crashing I’m afraid you’ll have to either uninstall the mod or upgrade to 1.1.

No problem, I was able to update to 1.1 and now eventing works.
Thanks for the nice mod.

Good to hear! In more recent versions the items are placed in a spidertron corpse instead of just being spilled upon death :)
