Hey!

Astral Sorcery treasure shrines contain a special Stone block, that regenerates when destroyed, and turns in to different ores. With Tool Progression in the same pack as Astral Sorcery, the special Stone block no longer drops anything, from any of the ores it generates. Having the correct tool and the harvest level the generated ore requires doesn't matter.
See this issue for more details: HellFirePvP/AstralSorcery#565 (comment)

I'm unfamiliar with AS, please provide more details.

If you've looked over the link, I'm not sure what more information I could give. Is there anything in particular you need to know?

• It's a very rare structure found between Y 40 and 10, I don't know of a way to find one easily, appart from turning its generation chance way up in the configs.
• I was thinking the issue could be a lack of harvest level on the stone block tile entity, but that doesn't seem to be the case, as it isn't registered in the blocks.cfg made by TP
• The user randomlypickedname was able to fix the issue by just removing TP, so in the case of my modpack, it seems TP plays a part

You can find them very easily using the advanced sextant from astral sorcery, just give it yourself in creative, at night right click the night sky, if you see a large start try and drag drop the shrine onto it, if it's not a shrine it won't work, if you look at the tool tip of the sextant it tells you what you're looking for

This is also fixed as part of 1.5.5
