If you’re experiencing script run-time errors and can’t be fixed by Smart Reset, or are having too many of them, you can get the latest v4.13.05.
Most of the scripts are Mono-compiled, which is a lot better at memory management.
Go through the Update Switch procedure, and when asked, choose “HUD only”. You don’t have to re-setup again, just transfer your gear from your current HUD (transfer will start automatically when you wear the new HUD).
This is a stop-gap before the upcoming HUD v.5
