You have mentioned in the changelog, that now you default to vanilla recipes for infinite tech? But it still adds only 100 more beaks for mining productivity each level, or 1000 for lab research speed, so clearly there is something still wring there :(

I like the mod, but it feels a bit cheaty to have these easy infinite recipes...

Mining Productivity was removed from the mod, as it is a base research. That's the Vanilla level. You are more than welcome to check it out for yourself. It's not uncommon for megabases to have over lvl 150 for this research. At that level, it takes 15,000 science packs, which is 15 rockets with satellites for each level. That is actually quite a bit in terms of Vanilla Gameplay. The formula is 100*(L-1). I could set some of the others to be the same, but I haven't put the time into determining what exactly to do.
