Spads crash when a certain player joins battle room

[Jools]

I think our xta autohost crashes when a certain player joins the battle room. In this case it's elderberry[Autohost].

The only thing I get in spads.log is this line before the crash:
20190831195625 - ERROR - [SPADS] <NoSmurfVoting> Minimum confidence is 90

NoSmurfVoting is a spads plugin that prevents several votes from same IP. But how can this plugin cause crash of whole autohost? Where should I look for more info in the logs? Sorry but I'm rusty when it comes to where all the log files are.
