All Heli_Light_02_F's TextureSources for OPF_F faction have the "factions" array defined as "faction" (missing S at the end), thus resulting in the textures meant to be exclusive to OPF_F being available to ALL factions - OPFOR, BLUFOR, INDFOR, CIV, everything. This is not an issue in the vanilla game, but any mod that adds the Heli_Light_02_F to any other faction will face the issue of these textures showing up when they should not, with no obvious error on the mod's creator's side. In fact, this issue will likely lead to duplicating this error under the assumption that the config is correct, while it's not.
Hopefully this issue can be fixed, so that modders won't have to locally fix it and/or lose their minds over a seemingly correct config.
