I've gotten these dye bugs from farming Cactuars:
soot-black
red ochre
oxblood-red
moss-green
I noticed that whenever i try and do the Undyed Hempen Cloth craft i seem to always fail it on the OB, i was level 10 and looking at a lot of databases even the one SE put out themselfs it seems to say i should of been able to craft it pretty simply.
I seemed to be able to craft most other things pretty simply, other then the things that said "your leatherworking is not high enough for this" etc. Did anyone else notice an increase in failure of trying to craft your own cloth or was it just me sucking badly at the crafting system
