building browser icons stopped showing?

[antizalfer]

i started modding/adjusting a mod of RTW and there where 3 unique buildings in that mod. After a bit of adding some units here and there the only thing related to buildings in my modding was the reactivation of buildingss that were disabled ie. some buildings where already there like the archery buildings and i simply added the names of factions to it. now the three unique buildings are still in the game and can be seen in the buildings tab (at the bottom) but they dont show in the buildings browser (technology trees).

Is there a limit to how much buildings appear in the building browser??? Even so, i left some factions' building browsers unchanged??

Buildings will not show up in the building browser if they have 'not' conditions in export_descr_buildings or if they are not the first buildings of that tree available at their given settlement level.
