I'm not totally sure what the bug's logic is, but when I have origins installed it tags most (not all) stone and stone-adjacent blocks (so far ores are exempt) as unbreakable, no matter what I have equipped. They behave like bedrock where I can swing at them infinitely without them taking damage. I did a mod purge to discover this mod as the source, but I do have 110~ mods installed, so it may have been a compatibility issue somewhere.

I did see some mention of Curios incompatibility and I do have that installed, but upon removing that mod as well it didn't fix the issue.

Minecraft: 1.19.2
Forge: 43.3.5
Origins: 1.7.1.7
Optifine: HD_U_I2

If there's a work around anyone might know that would be great, but I unless there's a fix I'll have to stick to building in creative or playing without the mod.

Thank you for your time!

UPDATE: Upon further testing it appears to be an issue with the feline origin, I'm going to see what I can do to get around/fix it.

Oh man do I feel silly! I went into the config and set weak_arms to "false", which solved my issue. so sorry for the waste of time!
