1) Assets not loading/turning white

You can let me know which assets specifically are not loading. Note that censorship or filters in your country or internet access can cause issues that not everyone else experiences.

One user ran into an issue where all assets were not loading -- fixed by toggling mod cache off to force the game engine to reacquire the assets online.

2) Where are subjugation markers/loyalty markers?

The neutral system markers on the loyalty space of each system are Stated objects. Hover the mouse/hand over the marker and use the 1-3 keys to toggle between different loyalties.
1 - Imperial loyalty / 2 - Neutral loyalty / 3 - Rebel loyalty
Use the 'F' key to flip a marker to reverse side. On Neutral and rebel loyalty systems, this shows a subjugated symbol.

3) Why are there some markers that are custom content and not original game content?

The contents match the real game version as much as possible. I did add a few minor improvements due to options/behavior available on the game engine for convenience/clarity.

Blockade markers -- reverse of Sabotage tokens has a custom 'blockade' symbol. this tells the scripts to not factor in production on that system as it is blocked by presence of enemy units. This adheres to the real rules of the game and just serves as an additional visual reminder/script tool.

Neutral markers -- simple image to represent a system that is neutral and not occupied; no different from an empty space in the real game.

Rebel Loyal/Imp Subjugated marker -- just overlaid Reb symbol on imp subjugated symbol to signify that it is still a Rebel loyal system as loyalty is not blocked by subjugation. this makes it easier to see rebel loyal systems than it is in the vanilla game.

4) Objective deck deals a card during setup before it is finished combining/shuffling the decks.

You're running at a higher FPS than intended. Coroutine pauses in scripts are based on frames; your fps is high enough that the delay is not long enough for actions to complete. Let someone else host at a lower fps or reduce your fps in-game. (I may get around to fixing these timings so 240 fps doesn't speed things up too much).

5) The Objective cards have the text blocked out in a black box.

As I've stated clearly in the mod description, this was intentional. FFG has had an informal policy in the past of not aggressing on vassal mods if mod makers block out text on key cards, forcing players to have the actual cards to reference. I have complied with this for FFG's interests.

Not going to debate the legality/morality here; I'm a fan of this game and FFG. I'm sharing my passion for this game by exposing others to it and enabling folks to play online with each other when in-person games are not possible. I believe this creates more impressions for the game which increases sales for FFG; I want to create some sort of incentive for folks to purchase the game. You should buy the game if you haven't already.

I decided to redact the objective cards. I stand by that decision. I may revisit this decision after the game has had more shelf-life.
