Oh, yeah, i guess that would happen...overwriting dosent clear the old data, it just overwrites it, expect for things that can be stacked (GameMods, sfx, etc) where it'd actually add that item to the list to the existing items.

Added to the bug list   Thanks heavenfall!

Actually, now that I think about it, there's no way to "counter"the inherent bonus from

        <GameModifier>
            <ModType>ResourceMultiplier</ModType>
            <Attribute>Materials</Attribute>
            <Value>1.20</Value>
            <Provides>+20% Materials</Provides>
        </GameModifier>

 since it's all additive. If I do <Value>1.20</Value> followed by <Value>1.0</Value> it just ends up with +120%.And if I do a negative value it reverses the whole building (<Value>-1.0</Value> = -120%)

Wow, this is rather inconvenient.

Have you tried:

        <GameModifier>
            <ModType>ResourceMultiplier</ModType>
            <Attribute>Materials</Attribute>
            <Value>0.80</Value>
            <Provides>-20% Materials</Provides>
        </GameModifier>

This sort of a system worked to counter the default bonuses from NPC professions and Sov histories.

Here's my question, I seem to be getting this overwrite but I am not modding files and placing them into a mod folder, I am simply modding the core files and leaving them where they are. Yet I still get this doubling and say 4 townhalls appearing on the tech tree description.

Apparently, it's quite like what BlackRainz has been having, yet I am not modding any tech files.

Many of the core Kingdom buildings XML files are literally broken where they have multiple copies of structures and some structures completely coded improperly. This is what's causing your doubling. Making a new data.zip file essentially breaks the game.

Doubling might also be caused by multiple input of the same building into a technology. Make sure your not just copying all the xml data and modifying it. You kinda need to minimize what your editing because the old stuff will still exist when you mod it... if that makes any sense.

Try removing the references to the harbors and such in your mods.

Making a new data.zip does not always break the game, actually most of the time it doesn't. There are many files you can change without it happening but there are also some that will cause this problem to happen. I have been playing around with it for a while and it doesn't always cause the problem. Or perhaps it didn't do it in other versions, maybe it's become a big issues in the new version?

For the record, when you're altering a spellbook under the <Spellbook> tag you have to re-state all spells. Despite <SpellBookNode> obviously being repeatable, it does not get saved when overwriting <Spellbook>.

ok i may have asked this in a way, but i still don't seem to grasp it.

I am remaking the data.zip, with core files only, yet modifiers and text are being duplicated, why is this when

there is nothing to duplicate from?

P.S. Plz don't tell me to put down the matches and leave the fire playing to adults

This does make it difficult to mod existing items.  I would guess that prerequisites also stack rather than overlay although that should cause less of a problem.

No adults here.  We're all kids with matches.

I edited the core abilitybonuses file and am not getting a double on it. the only thing for me that was doing it was improvements and I've since found a way to not have to edit that file for my mod.

i guess, in a way, it's too bad. i assume if it were an across the board thing, they'd have an easier time debugging, no?
