Last night, we had a purge at our volcano base, when we noticed a significant amount of attackers were dying in the lava before they could even be attacked. How it happened was they spawned on an island surrounded by lava before walking towards our base. Unfortunately, this led to the deaths of certain named purge thralls. While we were able to build a work around to that island for future purges, it still made me wonder if there could be a fix for this. Maybe make purges in the volcano lava immune?
In any case, best wishes
