When I start the game with this mod, all packs appear from the beginning to be researched, and after that all techs need all packs, which makes the process impossible. For example, the fast inserter tech needs the pack that uses fast inserters xd

Thanks for the report! Something strange is happening indeed.

Well, apparently, 248k mod introduces a White Hole that can duplicate almost everything, and the recipes it uses are available from the start (aside from having no White Hole, that is). It is understandable they are not unlocked with the White Hole technology, though, otherwise its description would be way too long.

To fix that, I eliminated the recipes that contain a catalyst which is also a requirement for some science pack, from the placement selection logic (since White Hole duplicates items instead of creating them from nowhere, that should work).

Check the 1.0.8 version.
