Default Unlock Checker

Default Unlock Checker is a troubleshooting tool. It helps if you can't find items like Torch, Campfire, etc. in your "Crafting" menu.

When used, it will say "are any default unlocks (like Torch) missing?" and "How many are missing". Unless it says "0 unlocks missing", you have a problem. More details (possible culprits, etc.) will be in your starbound.log.

Why are items missing?
This is caused by some third-party mod being written incorrectly (first of all, look at the page Incompatible for a list of mods that are known to affect "Crafting" menu).

You should identify that mod and ask their developer to fix it. You can also remove the incompatible mod.

I'm a developer of mod that has this issue, how do I fix this?
When written correctly, another mod adds default unlocks like this:

When incorrectly, like this (notice  instead of  ):

Second approach makes the order of "defaultBlueprints" unpredictable, thus causing unlocks of Torches, Campfire, etc. to end up in places where other items (those items that now require research and must have their unlocks removed) had their unlocks.

Always patching  instead of   will avoid many potential mod conflicts (not just with "Crafting" menu).
