Version: Alpha 20.5 (b2) with Undead Legacy 2.5.82; BackupMod 2.1.3

Wasn't doing anything special, just tooling around a random world.

System.InvalidOperationException: Collection was modified; enumeration operation may not execute.
at System.Collections.Generic.Dictionary`2+KeyCollection+Enumeration[TKey,TValue].MoveNext()
at EntityBuffs.Write(System.IO.BinaryWriter, bool)
at PlayerDataFile.FromPlayer(EntityPlayer)
at BackupMod.Services.WorldSaveAlgorithm.SavePrimaryPlayerData()

Unfortunately I cannot provide the complete stack trace as (AFAIK) 7DtD does not provide a mechanism to dump the console contents to a file; the above is manually typed out by myself, I think that is the most pertinent info.

Console logs are stored in a file somewhere under AppData, I believe it's %APPDATA%\7DaysToDie\logs on windows, but it may depend on how you installed the game files.

That's enough. It looks like the game cannot save some player data (I use the original saving algorithm from the game code, just without exiting to main menu). I've never encountered something like this, but I'll try to fix that in a few days, when I have time.
