The recycling recipes for Beacon MK2 and Beacon MK3 with Space Age enabled are wrong, the MK2 gives radars instead of superconductors and the MK3 gives accumulators instead of quantum processors.

Issue still seems to persist at the moment

I know this is late but I had the same issue but I was able to find a work around to it.

Within prototypes/intems.lua update the recipes to the correct version that are stored within prototypes/compatibility/space_age.lua

It seams that Factorio reads the items.lua and thinks those are the recipes for the recycling.

If you have issues I can copy my items.lua to pastebin or something.

This is still an issue, but lorddjinn's solution worked for me too. Thank you lorddjinn!

To add to lorddjinn's post:
For Windows, you need to make these edits in the mods folder in your Users/[Your Login]/AppData/Roaming/Factorio/mods/wret-beacon-rebalance-mod_[version number].zip. Grab the recipe items from prototypes/compatibility/space_age.lua and replace the incorrect equivalents in the recipes within prototypes/items.lua (not intems.lua--that was a typo).

I really prefer this style of beacon. Thanks wretlaw120 for making this mod!

To add further: using an if statement in prototypes/item.lua to check for the space age mod, then replacing the ingredients table if true preserves compatibility with the base game.

I have no idea how to do this in a different file, though. wretlaw120 seems to have tried to do this in prototypes/compatibility/space_age.lua, but it doesn't replace the recycle recipe when run from there.

MANY edits: various typo fixes. I cannot type today.
