I can't really figure if I should call this a bug or a suggestion.
https://mods.factorio.com/mod/timed_technology
When using this mod, all science packs are gone, and your Auto Research doesn't know how to handle this and just researches the next thing in line, even if its much-MUCH slower. I spent 2 hours waiting on something not paying attention and suddenly it finished, then lights got researched after that in like 2 seconds and I was all "wait, what?"
So, the mod should probably check time field rather than just the science pack fields.
