The error is due to the main NPC not being in a map. As it is not in a map, Herc most likely didn't initialize unit data for it (since it would be useless).   Either put it in a map or add a check to not apply unitdata for it. Here is how to do the 2nd option: OnInit: if (strnpcinfo(NPC_MAP) == "") // Not in a map, can't set view data end; setunitdata(getnpcid(), UDT_GROUP, 1); setunittitle(getnpcid(), "Goddess Statue"); end;  

That's weird... cvc was implemented together with the clan system, not having cvc would mean you don't have the clan system too. I do recommend updating though, since it is there since 2017. But here is the PR that introduced it: https://github.com/HerculesWS/Hercules/pull/1718  

I did a check and I saw that my emulator still doesn't have cvc, is there any diff or patch that I can add to my emulator?

Hello, I tested this on the latest hercules. It has error

I get this error when i set it to OnInit: setunitdata( getnpcid(), UDT_GROUP, 21); setunittitle( getnpcid(), "Goddess Statue" ); end;   then: OnInit: setunitdata( strnpcinfo(1), UDT_GROUP, 21); setunittitle( strnpcinfo(1), "Goddess Statue" ); end; Whole script: //===== Hercules Script ====================================== //= [ Heal & Buffs ] //===== By: ================================================== //= Euphy //===== Current Version: ===================================== //= 1.2 //===== Description: ========================================= //= Basic [ Heal & Buffs ] script. //===== Additional Comments: ================================= //= 1.0 Initial script. //= 1.1 Aligned coordinates with @go. //= 1.2 Fix variables and character stuck at healing //============================================================ - script Healer FAKE_NPC,{ .@price = 0; // Zeny required for heal .@Buffs = 1; // Also buff players?
