So I won’t edit the OP because of the huge amount of trolling about it. Need to unedited so everyone can confirm for themselves the trolls are just trolling.
The magnitude of the error is larger than mentioned in the OP - which for you all trolls: Was (some or all) Starter Systems with drone skills and The Forge with Caldari ship skills.
More skill groups are missing from as far as I can tell all effected areas, and at least The Citadel is also affected.
For any newbies reading this and confused on the skills and where they are actually supposed to be found: EDIT: Where skills on market are or should be .
