Some items not appearing in crafting menu

[dinoc]

So, I'm working on improving my current mod: https://mods.factorio.com/mod/Logistics_Bits_And_Bobs
but I've run into a problem. I'm making a new class of logistic and construction bots, and I have input all the information for their stats, I can summon them in via console commands, but they don't appear in the crafting menu.

When summoned via console commands, they work fine, but they don't show up in any of the normal places (hand crafting, assembly machine interface, etc.)

The new bots do have recipes, and it shows them under the tech that unlocks them.

Confusingly, they do show up in the logistics request filters.

Any insight as to why they're not showing up in the usual places?

Thanks.

Hmm. I think I figured it out, but I'll leave this post here for anyone who has the same problem.

I was loading a test save to test the mod in, but the save I was loading had already had a previous version of the mod running, with different tech options.

Running a new game to test the mod in cleared up my problem.
