Crashing on new Cube Draft (Jan 6th+ Forge Snapshot)

[HarlequinCasts]

Hi all. I grabbed the Jan 6th and Jan 7th forge snapshots, and ever since launching a new cube draft crashes.
Full disclosure, I regularly import my own custom cubes from popular websites, but something must have changed recently since this has been working for years. I see the nullpointer error begins with draftRankings being null. This error is generated using one of the default drafts (MTGO Vintage Cube May 2023).

java.lang.NullPointerException: Cannot invoke "java.util.Map.containsKey(Object)" because "this.draftRankings" is null

I was able to solve this hunting around for the Rankings clue. Apparently a new "rankings" subfolder was added to "res\draft\rankings". When I import new cubes, I have to modify the res\cube\ and res\draft\ folder so I tend not to copy patch information there. Did not realize this directory now exists and is important!
