Not a bug.  Both "Sorry ..." and "Sorry, ..." can be used here with equally apropos application. One implies "Sorry (that an error-state has occurred)..."  The other expresses the developer's sympathy with the user experiencing such.  Suggesting a missing comma is incorrect here is both incorrect and a waste of dev cycle resources in reporting.

Certainly, a lower-case "n" is a bug that affects core functionality of game-play and overall user experience, and should be tended-to and tracked with a software bug tracker.  😉

How is this a bug?

How in any sense does spelling "third-party" with or without hyphen affect code, function, game-play, user experience, ROI of those funding the dev. of Minecraft or those purchasing it?

This has zero impact on the final deliverable, game play experience, and is not a 'bug' nor should any reputable dev cycle or ITSQA bug tracker consider it one.  This is cruft.
