It's bugged, unfortunately. I set it to "hidden". This mod works on my end (I am the author), but the game won't let me publish it properly due to the publish button in the editor overwriting my custom data.xr. The editor thinks something like "OK, so the user hadn't made any changes, therefore, I write nothing to the files" overwriting my parameters. Doing token changes in the editor results in the editor overwriting my changes with the token ones. VERY nasty bug, since on my end it works perfectly fine, if I copy the mod to the folders manually without tinkering with the treasonous editor.
It seems that the only way for me to publish the thingy is to upload the *.pack directly to the net.
BTW, the main change consisted of doing this to the impossible difficulty in the XML:
<f_aiUnitProdTimeK>0.3</f_aiUnitProdTimeK>
<f_aiBuildingProdTimeK>0.5</f_aiBuildingProdTimeK>
the original values were 1 for both parameters.
Any modders who successfully published mods which required editing not in-game editor, are there any special tricks to publish it without the editor overwriting your changes?
