Angel's Mods from github are apparently close to working again. You have apparently disabled the script for them in RSO because they did not work in 2.0 before.
With the following fixes, they work as well as in 1.x:

Please note that I was not able to correctly spawn Angel's Infinite Ores without RSO, so this fix allows to play with Angel's Infinite Ores in 2.0 :)

It's probably best to not update RSO until we have Angel's mods almost ready for 2.0 release. We are still making a lot of changes!

I will wait for official go to with configs.

With angels 2.0 releasing today I tried enabling the script myself.
After some small fixes (replacing game.entity_prototypes checks with script.active_mods and config with config.nauvis in mainconfig.lua and angelsores.lua), it works fine as far as I can see with infinite ores spawning as expected.
But I'll wait for the official update :)

hoping for a quick update for this, looking forward to a new angelbobs playthrough

Are you willing to share more detailed instructions for the changes you made, while we wait for the official update?

If you can post the updated file somewhere and drop a link here I can add it right away. If you checked it works then it makes it easier for me (no need to prep mode setup etc).

Here's a gist with a diff and the 2 full files I modified (probably should have added that to my first post :V)

I've updated it a bit to use checking of ore entites and added - it's up in 21 now.

I'm seeing ores now. Thanks for the update Steve_Freeman and orzelek!
