i accidentaly used mcmmo with my tartarite headed thaumium everything else pickaxe and it made it a wood pickaxe, help please and fixing the bug would be awesome. thanks
Try to avoid using the mcmmo ability with the TC tools, it tends to happen this way and can be avoided by not using mcmmo abilities with the TC tools. As far as I am aware, this is an issue with those two mods and not the server itself. TC is coming with a ton of great updates with the next update so it all depends on when that will be implemented on the server. That being said I am not sure at all if that fixes this bug because it might be mcmmo that causes this to happen. Short conclusion: Using McMMO fast mining ability causes you to lose your great tool.
The abilities are not enabled for TC. It happens if you have a ability on a other tool enabled and switch then to the TC tool. This bug is already reported but no response from the devolpers: Tinkers Construct items turn into wooden items. · Issue #1760 · mcMMO-Dev/mcMMO · GitHub
