When I fight Zenth Marlet It crashes my whole setup

Maybe try and find a more reliable setup? Idk.

For my setup ive used Automasher from the mod as well as Autosplits and the kill count from Livesplit and everything on my end seems to run as intended. so i wouldn't think its the automasher is causing the crash. best recommendation would to be wipe all your setup and just start piecing it together again noting what causes issues and then youll know which toggles/settings to avoid. :D
