Only the POI and vessel names are in English, which is very odd.The game has been officially released, there should be no more parts that cannot be localized
Maybe you missed all the other threads out there about the 1.0 release: V1.0 does NOT even remotely mean it's finished, it just means they left Early Access. They JUST removed the Alpha Tag and started a new numbering. That's all that changed. From a development point fo view it just means that the basic CoreTech (like Building, Galaxy, NPCs, ...) is now implemented (but even that can and in some parts most likely will change based on the devs comments about the topic) Based on priority, my guess is that localization will be finished in a later stage or adapted as they go. /jmc
POI names are written on the blueprint itself by their creator (In the "spawn name" input box). There's no way to localize them since they only have a single input for names and no built-in translator.
