Does the bot stop or auto-stop?
Thus, you don't have the options turned on I guess stop.
I run HR on a low spec PC and wanted to save some resources by closing the bnet app.
But I feel like keeping the app open makes HS more stable.
Silverfish should consume less resources than the default HR AI, but running out of resources is another reason for HS crashes.
You can use the default AI and reduce the parameters or recompile Silverfish with lower parameters and test if this improves the stability.
Anyway a relogger would be great.
