I`ve never seen white battle cards in vanilla. There might be other mods that have the issue, but so far I`ve only seen this happening in RS2. While the game`s engine is the one unable to cope with a certain situation, clearly, the situation is created by the mod.
That I think is a myth. For example:
EB v1.0 which had no such issue
afaik had 2538 files in its UNIT_INFO sub-folder and 2555 files in its UNITS sub-folder
RS2(I`m looking at a beta which also had the issue) has only 1969 in UNIT_INFO and 2331 in UNITS.
Unless it happens in eb too and I don`t remember that then that`s that for the theory that there are too many cards.
Then there is dvk`s theory that because the engine is old it can not render the cards of the last units from EDU(from 446 up):

That also seems wrong because:
1. the same units(Machimoi Doryphoroi for example) may have white battle cards in the selection of a faction(ptolemaics for example), but show fine in the selection of another faction(parthia for example) at the same time. There`s only one EDU entry and only one export_units entry even if it`s used by more than one faction.
2. I (and others too afaik) have a full (500 entries) EDU in other(other than RS2) games and there`re no white battle cards showing.
As I`ve told tone a while ago, the problem needs to be more systematically analyzed, preferably via a public thread in the workshop collecting all the data in one place so that everyone might contribute ideas. Blaming everything on the vanilla engine is both rather unfair imo and won`t lead to solving the problem either.
