The only known incompatibilities are with the Confection, the Depths, and — to a much lesser extent — Avalon.

It has world creation Incompatibilities with MoreBeams for some reason, It always crashed on world creation

That's odd, I'll have to look into what it changes about worldgen;
Is there any more information you can provide about the issue, such as an error message or how you determined that the incompatibility was between these two mods?

Could there be possible compatibility errors with Magic Storage? As I don't see a way of getting Demonite/Crimtane to craft the storage upgrades? Perhaps The Stars Above as well, since they ask for corruption boss kills, thought I haven't gotten to that part yet.
I chose the Riven evil biome when making the world

The issue with magic storage is due to a strange choice in its implementation, which is supposedly planned to be fixed soon, we have the sprites ready for the appropriate equivalent upgrades, but until magic storage supports other mods adding storage upgrades using shimmer will be necessary in order to get that tier of upgrades.

Yeah I already entered a dead world of mine to get demonite ore after killing Eye of Cthulhu, tho I'm still curious would there be any issues considering this part of Stars Above https://i.imgur.com/3qmD2sv.png

Have you beaten the World Cracker and found that this is still locked, or are you just making the (rather reasonable, given the phrasing) assumption that it's actually tracking killing the boss rather than just using the vanilla flag?

If it's the former, then I'll do what I can to make the mods work together properly (and for the time being, Terraria Origins makes it substantially easier to get the materials to make an artificial crimson or corruption), if it's the latter then the extent of the issue may just be that this text is inaccurate.

I've yet to kill it, I'm just wondering whether it will work in the near future.

In that case it probably already works, TO sets the same vanilla flag that both of those bosses set, since it's necessary for vanilla content like meteorites and the Tavernkeep NPC, and potentially a large amount of modded content.

Okay, thank you for your promptly replies, will let you know if there's any issues then.

There's a slight interaction issue with calamity in pre-hardmode.
Acquiring blighted gel is either impossible with Riven/Fiberglass evil biome or extremely tedious ( Farming the Crimson floating island ) and the Spug Flesh doesn't count as "Any evil block" for the Overloaded Sludge crafting to summon the Slime God

This also regards few other accessible items from regular corruptions, like the Vile Thorn/Crimson Rod for Night's ray crafting and such, also including the Perforators and Hive Mind access.

don't mind the worldgen previewer, it happens without that mod aswell

error message without worldgen previewer.
