Hey guys, Something new and weird is going on with the art assets in my mod going missing. This didn't used to happen prior to Gathering Storm. The modifier MODIFIER_PLAYER_ADJUST_VALID_IMPROVEMENT is used by City States that allow you to build unique improvements like the Alcazar and Nazca Lines. It can also be used in any general case where you want to enable a civ to build an improvement. The issue I'm having is that if I assign this modifier in a way that crosses the threshold between expansion packs (e.g. providing an expansion improvement to a non-expansion civ) the graphics don't show up in game. Instead you get the "missing asset" exclamation point in game. For some reason this is also happening with assigning non-expansion Districts to expansion civs, using the trait system. For example, if I use a Trait to assign the Mbanza to Zulu and Nubia, it vanishes. I'm hopeful I'm just missing a dependency somewhere in the set up of the mod. Anyone tackled this issue?
