Reforged Incompatible?

[Dealman]

Me and a friend were looking into trying this with Seamless Co-op + Reforged, but it seems that Reforged is incompatible with the current version?

Upon attempting to merge the mod, I receive this error:

System.Exception: Failed to edit event scripts in enemy randomizer, likely because merged mod is incompatible. See spoiler logs for details.
   at RandomizerCommon.EnemyRandomizer.RunGame[TMap,TEnemy,TRegion,TGenerator](RandomizerOptions opt, Preset preset, Dictionary`2 maps, EnemyEditor`4 enemyEditor)
   at RandomizerCommon.EnemyRandomizer.Run(RandomizerOptions opt, Preset preset)
   at RandomizerCommon.Randomizer.Randomize(RandomizerOptions opt, FromGame type, Action`1 notify, String outPath, Preset preset, Messages messages, Boolean encrypted, String gameExe, String modDir)
   at RandomizerCommon.EldenForm.<>c__DisplayClass61_0.<randomize_Click>b__0()

Using Randomizer v0.6.1 and Reforged v0.5.13A. Using the automatic mod engine installation steps.
