StrawberryDonut Might be related to your issue, might not, but there are already two (and a half) issues I see on those screens (kudos for informative screenies):
1. Your AAU version is 1.5.3 - grossly outdated. Use the Modern Installation Guide link in "Other Sources" in OP instead - that way you can get the up-to-date version of everything...which kind of ties into the next issue:
2. Your data folder shows "ppx" files AND "pp2" files - the two formats are incompatible, you cannot have both enabled at the same time - either, or. You
can use PP and PPX mods together. PPX is supposed to supercede PP2, anyway.
2.5. Checkboxes: you can use PP and PP2 together
or PP and PPX,
but not PP2 and PPX. Make sure the respective boxes are [un]ticked in the AA2Unlimited tab. For example, your screenshot of that tab shows PP and PP2 boxes ticked, and your data folder contains a bunch of PPX mods, none of which are active since PPX box is unticked.
Summary: AAU outdated - update. And your data folder shows PP2 mods and PPX mods - they are NOT going to work side by side. Unless you have a specific reason to stick with PP2, go with PPX instead.
