So far the Lighted Poles recipes have worked fine, the lighted variants for Pole 1, Pylon1, Substation 1 and Pole 2 became available together with their base variants. However, now I've reached green science and the recipes are suddenly gone. (Sorry, I did not notice which tech specifically triggered the change.)
Looking at them with FNEI shows that Lighted Pole 1 and 2 depend on Energy Distribution 1 (ok), but also Packaging 4 and Woodworking. For Pylon 1 it's Iron Working 1 and Energy Distribution 2 (ok), but also Packaging 5. For Substation 1 it's Mass Production 7 that's suddenly stopping it from being available (my guess).
I did not update the game or any mod since I last crafted lighted poles.
And in case it's not clear: I'm not asking for compatibility, just that unlocked recipes don't get locked again later (aside from Nullius' progression recipes).
PS: FYI, LPP recipes are all "1 pole + 2 lamps-> 1 lighted pole". It has no techs of its own and copies the recipe tech requirements from the poles' crafting recipes (plus those of the lamp's crafting recipe, I think).
Edit: I'm on 1.5.25 and 1.9.0 for LPP. Both latest as of now.
