Hello, got the same error with no particular player action during gameplay : https://imgur.com/TtMWxl8
Here's the steel array setup I made to use Burner Leech : https://imgur.com/Z6rCJUf

It seems to crash at a specific time after a save load, here's the save (mod heavy) if you want to reproduce the issue : https://easyupload.io/53kvsu (15 days expiration, password : factorio)

To workaround the crash I loaded the save and filter-deconstructed the steel array burner inserter, so it seems it was indeed where the problem happens.

Appears to be resolved in 2.1.3
Please let me know if this is still an issue for you both.

Hello,

Thanks for the quick update, I updated and loaded up my "bugged" save, the crash doesn't seems to happen anymore so far !

Another way to reset this for testing is to load the game without the mod enabled, save, enable mod and load; this will force a rebuild of the global table.

Glad to hear that it seems to be working for you though.

since some mods were not updated yet, i canceled my playthrough of a fantario game and started from scratch. all worked well until i wanted to place the first burner inserter which crashed with exact the same message as above:

i am using the newest versions (as of last afternoon, factorio 0.18.4 and burner leech 2.1.2) and lots of other mods, including fantario, burner fuel bonus, more long inserters, and maybe even one or two other mods that deal with inserters.

while writing this, i checked the mod portal and there is a new version 2.1.4 from today ...
testing now ...
it seems to work !

Just be careful with burner fuel bonus, I'm not 100% sure on compatibility at this stage
