Some mods do not support having a block/item with an hyphen in it, like the chisel:sandstone-scribbles block, it should be named chisel:sandstone_scribbles, to follow naming convention

That would break worlds. I'm not doing that just because one mod has broken parsing. This is a bug on their end.

no problem, issuing AtomicStryker for that then

Jesus Christ. GitHub doesn't accept formatting from emails. Pipe character |

any news on that?

Why wouldn't they support it? That is a perfectly valid registry character

because Ruins use hyphen to split block name from metadata(I know, not a standard way of doing things either)
and as far as I know, only Chisel use hyphen in block name, and not even for that many block(wood planks and sandstone only)
changing to underscore would fix this very quickly, and normalize name
