Error Running Patch

[LilSpoonle]

I've been using this patcher for about a year now, but after an extended break from Skyrim the patcher always gives an error when run.

Here's the error:

Updating newly generated leveled list references. System.NullReferenceException: Object reference not set to an instance of an object. at TrueUnleveledSkyrim.Patch.LeveledItemsPatcher.ChangeNewLVLIEntries(LeveledItem itemList, IPatcherState2 state, ILinkCache linkCache) in C:\Users\***\AppData\Local\Temp\Synthesis\4wmwmifv.ocj\Git\dx302d5p.r4d\Runner\TrueUnleveledSkyrim\Patch\LeveledItems.cs:line 182 at TrueUnleveledSkyrim.Patch.LeveledItemsPatcher.PatchLVLI(IPatcherState2 state) in C:\Users*\AppData\Local\Temp\Synthesis\4wmwmifv.ocj\Git\dx302d5p.r4d\Runner\TrueUnleveledSkyrim\Patch\LeveledItems.cs:line 250 at TrueUnleveledSkyrim.Patcher.RunPatch(IPatcherState`2 state) in C:\Users*\AppData\Local\Temp\Synthesis\4wmwmifv.ocj\Git\dx302d5p.r4d\Runner\TrueUnleveledSkyrim\Program.cs:line 40 at Mutagen.Bethesda.Synthesis.SynthesisPipeline.<>cDisplayClass16_02.<<AddPatch>b__0>d.MoveNext() in D:\a\Synthesis\Synthesis\Mutagen.Bethesda.Synthesis\Pipeline\SynthesisPipeline.cs:line 106 --- End of stack trace from previous location --- at Mutagen.Bethesda.Synthesis.SynthesisPipeline.Run(RunSynthesisMutagenPatcher args, Nullable1 exportKey, IFileSystem fileSystem) in D:\a\Synthesis\Synthesis\Mutagen.Bethesda.Synthesis\Pipeline\SynthesisPipeline.cs:line 631 at Mutagen.Bethesda.Synthesis.SynthesisPipeline.<>c__DisplayClass45_0.<b0>d.MoveNext() in D:\a\Synthesis\Synthesis\Mutagen.Bethesda.Synthesis\Pipeline\SynthesisPipeline.cs:line 496 --- End of stack trace from previous location --- at Mutagen.Bethesda.Synthesis.SynthesisPipeline.HandleOnShutdown(Func`1 a) in D:\a\Synthesis\Synthesis\Mutagen.Bethesda.Synthesis\Pipeline\SynthesisPipeline.cs:line 881 at Mutagen.Bethesda.Synthesis.SynthesisPipeline.Run(RunSynthesisMutagenPatcher args, IFileSystem fileSystem) in D:\a\Synthesis\Synthesis\Mutagen.Bethesda.Synthesis\Pipeline\SynthesisPipeline.cs:line 484 at Mutagen.Bethesda.Synthesis.SynthesisPipeline.<>c__DisplayClass44_0.<b__1>d.MoveNext() in D:\a\Synthesis\Synthesis\Mutagen.Bethesda.Synthesis\Pipeline\SynthesisPipeline.cs:line 456
