Any chance of a Krastorio 2 compatibility mode? K2 makes spidertrons require fuel (DT fuel cells for the default spidertron). It would help balance if this mod's spidertrons could require some sort of fuel as well; rocket fuel or solid fuel might make sense for the lower tiers?

I am rather conflicted about what to do with this. One thing is I don't want to enforce fuel on all spidertrons if K2 is enabled and have nothing when it is not. So there are two options that come in mind. 1. Make this feature enablable in mod settings. 2. Make "addon" mod for this. In both cases I think it should add fuels to spidertrons regardless of K2 (of course with compatibility with it).

Having a toggle in the mod settings is the exact same solution that K2 uses, so it seems to me like the best the option.

I have added the mod setting. It is also compatible with K2. Please, let me know if anything doesn't feel right, or everything seems good.

Doesn't seem to want to be fueld by processed fuel (item name: processed-fuel) from AAI Industries, which would be nice since it integrates so nicely with K2 and SE

Thanks for feedback, I have now added processed fuel from AAI industry.

Oohh, thanks!

Found a bit of an issue, can use stacked processed fuel, but not unstacked

Can you tell me which mod for stacking did you use? I tried with deadlock stacking, which worked fine, but stacked version could not be used as fuel at all.

Here's links to each:

https://mods.factorio.com/mod/Deadlock-SE-bridge
https://mods.factorio.com/mod/Deadlock-AAII-bridge
https://mods.factorio.com/mod/deadlock-compressed-aai

I suspect it has to do with that last one, but it doesn't explain why I have the exact opposite issue, where it lists the stacked fuel as usable but not the non-stacked fuel

TLDR; Your suspicion about deadlock-compressed-aai was correct. However I have added vehicle fuel also to lowest tiers of spidertrons and that should resolve your issue.

The issue was that Krastorio2 changes category of processed fuel, to "vehicle-fuel", however deadlock-compressed-aai generates stacked version with original category "processed-chemical", which lowest tiers of spidertrons would not accept as I considered that category to be slightly more advanced than coal. I have also added vehicle fuel to lowest tiers of spidertrons, as that probably makes more sense anyway, so that should "solve" the issue.

Awesome! And yeah, does explain how my issue was the opposite
