Hello Komissar Rudinov.
Return to the screen before 1.0. No DLC buttons, no RimThemes buttons. That's it.

What's this mod for?

v1.3.1
Now removed the RimThemes's theme switch button from the start screen.

This update give perfect classic screen, but you can't even switch between themes. If you want to switch themes, disable this mod from the mod list. Then, it will return to the default theme of RimThemes and you can switch the theme.

IMPORTANT
[1.2] Currently, a harmless red error is recorded when starting the game, but it is possible to select the theme. However, depending on the game settings, the mod list will be reset due to an error, so it is not recommended to use it.

Welcome! Have a fun Rimworld!

@Proxyer ooh I apologize!!
I play without steam, from the sendowl downloaded game.
I use rsync to sync the mods from Steam over to the games Mods directory, and the "RimThemes/Core" folder was not being synced because I forbid to sync folders named "Core", so the theme wasn't being copied.

Thanks to your screenshot I found the mod "Without Steam" which will help me to run the game directly from the steam directory in the future.

Thank you so much for your patience and help! :)

In the theme selection screen, if you enter "Core" in the search, do you find it? In some cases, the order of the themes may be different.

@fireglow
I tested it. Perhaps with over 90 mods.

sorry to trouble you, but could you please unsubscribe(delete) Mod and then subscribe again? Recent versions of Steam may throw up errors in updates, and such cases can be normalized as described above.

@Proxyer sorry, I just can't get the Core theme to display in RimThemes.
I've tried various load orders, the last one is:
Harmony
Core
Royalty
RimThemes
[SubMOD] Classic Vanilla Theme
Animals Logic
HugsLib
...
but no Core theme :<
Do you have an idea what's wrong?

ok! now need Harmony.

sorry I deleted my comment again because the theme isn't yet showing up in the list.
I g2g now but I will re-check later! Then I will give a thumbs up :))

@fireglow
