I have this problem:
- the models are completely incorrect.
- there is partially no hud and no clickable objects on the start date selection screen, as with the usual incompatibility of the mod with the game version
- Sometimes there is no hud even in the main menu.
I tried it on the new (1.13.1/3) and old version (1.12.5). I also tried the "open beta" version. I turned off all the DLC, especially "road to power". There are no other mods.
