Errors in console and switching themes doesn't work anymore after upgrade to 1.3.1

[Thilo M]

Recently I wanted to upgrade from 1.2 to 1.3.1.

1. I deleted my MetroidvaniaSystem directory in my addons folder
2. downloaded the project zip from GitHub
3. extracted the MetroidvaniaSystem folder to addons.

When I now open my project:

• errorrs show up in console when I open (screen 1)
• same errors show up when I add a new room to the existing map everytime I do
• if I switch the theme all my rooms are gone (screen 2)
• on the current theme (SotN) the map looks different than before. The background of the rooms is now blue, it was black/translucent before (screen 3 & 4)
• if I switch themes, click around and switch back, I get a map with mixed themes (screen 5)

Screen 1 - Errors:

Screen 2 - Switched Theme

Screen 3 - before:

Screen 4 - after:

Screen 5:

Additional Notes:

• adding the sampleproject and extension directory don't change anything
• the game still runs. The Map is now blue instead of black, though and I cannot switch themes
• I haven't tried any of the new features like the new modern map

Were there any documented breaking changes from 1.2 to 1.3.1 that I missed?

4.3, sorry forgot to mention.

Sorry I didn't notice earlier. Looks like you are using the version from GitHub. It's still experimental, get the addon from AssetLib for now.

That seemed to fix it, thanks
