"Text FileArchive missing label" generally has something to do with versions, IIRC. Look at the top of the file for things as

or

I would try disabling engines. I did essentially this for black holes in E4X, but I'm not sure of any pull abilities that don't disable engines.

I'm trying to mod more research arrows into the game, but I can't figure out how.

Currently, I'm just trying to get the research window to display an arrow leading from a prerequisite to the tile just above it. This arrow already exists in the game files! BackdropInGame.dds already has this exact arrow, and it's already listed in Screen-InGame.brushes as "ResearchWindowArrowUp1".

Except ResearchWindowArrowUp1 isn't included under the arrowBrushes section of ResearchScreen.window. The problem I'm having is, any attempt to alter what's listed under arrowBrushes breaks the research window UI.

Adding the line "Up1 "ResearchWindowArrowUp1"" before "Up2 "ResearchWindowArrowUp2"" produces this:

All other research windows are similarly broken. (This disaster generates the expected flood of error popups in Developer.exe)

Trying to tease out exactly what the game will accept (new arrow listed at the bottom of arrowBrushes, or simply changing the twos in "Up2 "ResearchWindowArrowUp2"" to ones) just yields the same broken research window every time.

Am I doing something wrong? Is there something important I'm overlooking, or is it just impossible to add new arrows to the research window? I'd greatly appreciate any help with this.

EDIT: Nevermind I figured it out, I'm an idiot  

I've been trying to add 2 extra research levels to RESEARCHSUBJECT_COSTDECREASERESOURCES.entity. The research has 2 extra levels but the cost decrease for the extra levels doesn't apply, any idea why?

The only change I made from the original was in this line:

Hi there - I have a few questions I'd hope to get an answer to.     I'm specifically for looking for certain kinds of mods that have been made, but there's so many it's hard to be sure whether what I'm looking for is out there (and if not, if it can be created), so I'll just post it out.

1.  Is there an Improved AI Mod standalone?

I realize that no AI will ever be as good as a human most likely and that you need quite the programmer to make a good one, but if there actually is an Advanced AI somewhere for the game, that would be nice.

2.  No Fleet Income Penalty when not at cap intervals

I like the Tax penalty when upgrading to new fleet levels, but having the tax be retained when your fleet is destroyed has simply never made sense to me (and can make recovery nigh impossible, which one would think would be the point).  Are there any mods that make it so that the tax is only applied if your ACTUAL fleet usage is enough to enter the taxation zone?  (e.g. 0-100 fleet points = no tax, regardless of level upgrade; 101-250 = 9% tax regardless of level upgrade, etc...)

3.  Simple Balance Mods

I realize some mods do balance while expanding the game, I'm just wondering if there are mods that ONLY do balance and nothing else.  Following some games and reading up on things I've noticed that some Capital Ships (for example) are almost never used because they are considered underpowered - the very concept that such an animal could exist doesn't make sense to me...I think everything should have its place and I'm wondering if any Balance Mod has addressed this to the community's satisfaction.

Might have more questions later but for now this will do.     Thanks!
