[BNW] Buildings not showing up in city construction for no appearant reason!

[Rifler]

Good Evening,

still working on my Mod-Mod, switched back to the earlier builds ontop of Communitas, primarly because I figured that the Community Patch project has a horrible performance. However, for absolutely no appearant reason my custom buildings won't show up in the citys building menu. To be honest I'm trying to fix this since countless hours, and it drove me mad to a point were I had to figure, that the Civ5 engine is the most *****y engine I ever built mods on. The problem here is, it worked, but then out of nowhere it stopped working. I fixed any database/lua error warning, I made tripple shure all the usual prerequisites are met. I tried everything, bu those damn buildings will just not show up inside the city construction. See this screenshots:

Spoiler :

As you can see the buildings are perfectly showing inside the tech tree and the civilopedia, but not in the city. For convenience reasons I limited the buildings to one, to better demonstrate the problem. I want to mention again, if there was a comprehensive error that I could review inside the log files, I wouldn't get the buildings to show up in game at all, as I know if you create an error inside the file, the whole file will be ignored by the engine. I also have to repeat again how dispaired and mad I am. I restarted this project more then 5 times already, primarly because the engine was bugging out on me, and I evolved in skill and wanted to accomplish more and better.

But now I feel I'm at a point I have no more control over this engine. As I said, there is absolutely everything exactly as it should be. I tripple...quadruple checked. I browsed the net for fixes. I rebuilt the Mod from scratch, over and over and over again. I can't count how many times I saw light at the end of the tunnel, just to be stopped by an uncomprehensive, unfixable bug...this engine got to be the single most horrible engine I ever modded games on, and I'm not talking out of the blue here, as I modded a huge amount of games. However, here's the data and logs. Please help me, I don't want to abandon my work again...I'm sick of it...

               The concept of a tree of life has been used in science, religion, philosophy, mythology, and other areas. A tree of life is a common motif in various world theologies, mythologies, and philosophies. A mystical concept alluding to the interconnection of all life on our planet; and a metaphor for common descent in the evolutionary sense. The term tree of life may also be used as a synonym for 'sacred tree'.[NEWLINE](Quoted from en.wikipedia.org/wiki/Tree_of_life)

I'm uploading the logs. I'm aware of the tech errors, the others are originally created by the communitas mod. Those tech errors are related to invoking text directly into the building rows, so that's not the problem. Because I got this errors as well, by the time it was still working. Adain, nothing has been changed. I'm doing frequent backups and major backups when a new milestone is reached, I do it all very carefully and decent. I had two of the buildings in game, I believe it started after adding the third building. Going back to an earlier backup, importing the building all over again, resulted in the same issue over and over again.

Ok, figured the...
<Gold>1</Gold>
...isn't supposed to be there. Removed it, rebuilt, tested again. Still not working. See I'm working on it, I really do...

Btw. wasn't the whole file supposed to be corrupted and so the buildings shouldn't have showen up at all? Neither in tech tree and civpedia? Dat enginge...seriously...

Edit: Yes, yes...I see it...TXT_KEY_BUILDING_TREE_LIFE_STATEGY...it is referenced in the buildings row as well. Fixinf, rebuilding...NOPPPEEE!!!

Edit 2: Btw. it doesn't matter if I'm adding buildings to the existing file, or import a completely new file to the database. The buildings will show up in techtree and civilopedia, but no inside citys.

I got it fixed. It was a combination of trial and fail, single out small rows of code to figure the problem. Down to the core it's related to the following issue, or any combination of it:

1. buildings that define as wonder, can not be combined in a file with buildings that define as buildings
2. the <MaxPlayerInstances>1</MaxPlayerInstances> tag must be always attached to a buildingclass that defines as wonder
3. if there is a building inside the combine file that has the <MaxPlayerInstances>1</MaxPlayerInstances> tag, it will omit all other buildings inside that file for the city production screen
4. the same is true for units that define as great person, special unit, or normal unit
5. the <ArtDefineTag>MONUMENT</ArtDefineTag> tag probably also stands in relation to the whole issue, though I don't now how exactly it interferes
