So 2 things which aren't precisely bugs but affect gameplay negatively.
1) Liquid metals.
In SE there is a point to these. The SE caster building seems to be redundant with one from a mod I have not played, and liquid metals seems to be a way to waste resources instead of an important way to boost them in the midgame. I don't know why they are needed unless they serve a purpose I am unaware of? Or, we should get a way to benefit from them like in SE.
2) A bunch of recipes missing signals.
Specifically, the dirty water to resources ones from the filtration plant. I rather need these to set recipes, so I can use a dozen filtration plants instead of literally hundreds. There may be more missing, I haven't done an exhaustive search.
If I find more stuff, would you prefer I make a new topic so you can put a tick next to it? It felt like spamming, so I can make new topics or reply here if I find more stuff in the future - pretty sure I will.
Also, thanks for looking after this mod. Your work is appreciated!
