Heyo! That's hotfix 5.2.1, which we just put live.

We know the patches have been abnormally large in size as of late. This is because we've changed our patching structure to one that doesn't bloat the game over time, but we've found that it leads to patches turning into extremely large downloads.

We're currently looking into improving our building and patching process to avoid this issue, but it may take some time. In the meantime, we apologize for the inconvenience of these large patches!
