=== Assistant: Perfect! ===
Perfect! Let’s make this thorough so your DRGBase creator friend has everything they need. I’ll give a safe patch and a full explanation of the issue, including context from your crash.

==== 1. The Issue ====
* Error:

<syntaxhighlight>lua/entities/drgbase_nextbot/relationships.lua:524: bad argument #1 to 'upper' (string expected, got table)

</syntaxhighlight>
* Cause: string.upper() is called on a table instead of a string.
* Function involved: UpdateRelationshipWith in relationships.lua.
* When it happens: Sometimes during NextBot spawning (SP or MP) when the relationship data is a table, not a string.
* Impact: NextBots continue to work; this is a console error only.

==== 2. Minimal Safe Patch ====

Edit lua/entities/drgbase_nextbot/relationships.lua around line 524. Wrap the string.upper call with a type check:

<syntaxhighlight lang="lua">-- Original line (approx)
rel = string.upper(rel)

-- Patched version
if type(rel) == "string" then
    rel = string.upper(rel)
else
    print("[DRGBase][Warning] Relationship is not a string!", rel)
    return -- skip updating if invalid
end

</syntaxhighlight>

Explanation of the patch:
* type(rel) == "string" ensures we only call string.upper on strings.
* If rel is a table (or anything else), it prints a warning to console instead of throwing an error.
* return prevents the invalid value from breaking UpdateRelationshipWith.

✅ Safe for both Singleplayer and Multiplayer.
✅ Stops spam errors.
✅ NextBots continue functioning normally.

==== 3. Optional Improvement ====

If you want DRGBase to handle tables automatically (e.g., multiple relationships at once):

<syntaxhighlight lang="lua">if type(rel) == "table" then
    for _, r in ipairs(rel) do
        bot:UpdateRelationshipWith(otherNPC, r) -- recursive call with correct type
    end
    return
elseif type(rel) == "string" then
    rel = string.upper(rel)
else
    print("[DRGBase][Warning] Relationship is not a string!", rel)
    return
end

</syntaxhighlight>

This way, any table of relationships will automatically be processed, preventing future similar issues.

==== 4. Why You Saw It in Singleplayer ====
* Some NextBots or mods might store relationships in a table by default, even in SP.
* Any addon or custom NPC might trigger the bug if it calls UpdateRelationshipWith with a table.
* DRGBase didn’t break SP functionality, so it’s easy to miss unless watching the console.

==== 5. TL;DR for the Creator ====

Summary you can send them:

: DRGBase throws bad argument #1 to 'upper' (string expected, got table) in UpdateRelationshipWith.
: The root cause is that string.upper() is called on a table instead of a string.
: Happens in SP and MP when a relationship is stored as a table (e.g., multiple default relationships, custom NPCs, or addon conflicts).
: NextBots still function, but the error spams the console.
: Suggested patch: type check before calling string.upper to safely skip or iterate tables.

If you want, I can also write the full modified <code>UpdateRelationshipWith</code> function ready to just drop in relationships.lua—so you don’t even have to patch line by line. This version would fully handle tables safely in SP and MP.

Do you want me to do that next?
