Greetings!

Here are steps you need to take to fix this quest:

1. open file: Steam\steamapps\common\Sea Dogs City of Abandoned Ships\Program\characters\LSC_Q2Utilite.c

2. Ctrl+F: void BerglarsInit()

3. check this method for the name of colony in which you would like to recover a guy you missed

NOTE:
in C "{" and "}" are the beginning and the end of method;
"//" is commenting everything to the right;
"/*" and "*/" comment everything in-between them

4. copy part from comment above section you need and until comment below (or end of method), like as this:

//============> ãðàáèòåëü â Ñàíòà Êàòàëèíå
pchar.questTemp.tugs.berglarSantaCatalina = "SantaCatalina_Cave"; //óêàçàíèå ãäå çàáèâàòü ñòðåëó
pchar.questTemp.tugs.berglarSantaCatalina.hp = 230; //ñêîëüêî HP
pchar.questTemp.tugs.berglarSantaCatalina.locator = "gate_back"; //âûõîäíîé ëîêàòîð
sld = GetCharacter(NPC_GenerateCharacter("BerglarSantaCatalina", "citiz_9", "man", "man", 25, SPAIN, -1, false));
sld. name = DLG_TEXT[10];
sld.lastname = DLG_TEXT[11];
sld.rank = 25;
sld.city = "SantaCatalina";
sld.location = "SantaCatalina_town";
sld.location.group = "goto";
sld.location.locator = "goto5";
sld.dialog.filename = "Quest\Berglars.c";
sld.greeting = "pirat_quest";
GiveItem2Character(sld, "pistol4");
GiveItem2Character(sld, "topor2");
sld.money = 30450;
sld.talker = 7; //íà÷àòü äèàëîã
SetSelfSkill(sld, 10, 10, 80, 50, 80);
SetCharacterPerk(sld, "CriticalHit");
LAi_SetHP(sld, 1.0, 1.0);
LAi_SetLoginTime(sld, 6.0, 21.99);
LAi_SetCitizenType(sld);
LAi_group_MoveCharacter(sld, "SPAIN_CITIZENS");


(I added space in "sld. name" because it was perceived as a link for some reason.)

5. find file: Steam\steamapps\common\Sea Dogs City of Abandoned Ships\Program\scripts\tavern.c

6. make a reserve copy of it!

7. right before end of first method insert the part of code you copied from LSC_Q2Utilite.c and press Ctrl+S to save

8. run your game and sleep at the tavern until next morning

IMPORTANT:
game cannot be minimized;
if you have ADHD or something like it, fix the tavern code right now;
don't forget to save game before quitting

9. go check for that guy, just to be sure

10. erase the part of code you inserted in tavern.c

That ought to help.

Thank you for reading and good luck!
