I play with Lignumis and for being able to use some level of Smart Inserters already on Lignumis, I modified them to use wood science packs and such. But all the Smart Inserter techs aren't showing up on a new game when using my compat patch for that. /c game.print(game.player.force.technologies["si-unlock-cross"].enabled) for example returns false.

I coded the compat on an existing game, were Smart Inserter techs required automation science packs. That worked to change them. But never tested it on a fresh game until now and nothing shows up.

Happens in Factorio 2.0 and 2.1

Ill check, can you send me an empty save for the modlist?

I just wanted to create a new save for you, and you know what's fun? In that save it's showing up.

Both saves are for 2.0

Yes, I have the same issue. It is caused by using the "Smart Inserters" mod; the technology displays correctly and production works fine when the mod is removed, but the research progress disappears once the mod is added back. I am playing with the "Exotic Space Industries: Remembrance" mod, which includes a "Crane" technology that allows for crane production. With the "Smart Inserters" mod installed, the Crane technology can be researched, but the cranes themselves cannot be produced, and the item does not appear in the inventory list.

vslley76, yours is a different problem, your seems more like a setting problem, SmartInserter ha s asettings that disables long inserter, a crane should be calculated with range at least 2 sinze the base is bigger, so the crafting will be hidden, create a new bug report and share an empty copy of the world to retrive teh modlist

I haven't thought about it that is the setting problem,thanks!
