so recently on multiplayer, i found a Bone Tool Rod, a Paper Binding, and a Blue Slime Pickaxe head. so i made a tinker's tool with it. i added an emerald and a diamond to it. later i had to log off for a few minutes, and whenever i log on now it crashes. when i put the emerald on the tool it said it had incorrect data and that i should craft it. so i did. but it still had incorrect data. i assumed it was a bug. so i reloaded the pack. then logged in. i crashed again. and again. and again. and over and over again. i went in singleplayer and recreated what i did online, and got the same result; a tool with incorrect data. i assumed it harmless, but clearly not. i tried changing out tool parts but nothing happened. so i believe i might need to get my inventory wiped, or try to remove the tool from my inventory. I'd prefer the tool be removed. If my inventory needs to be reset, I'd like my claim located and waypointed so i can go back, and my inventory contained a heavily damaged diamond chestplate, some slightly damaged osmium boots and legs, (idc if you keep the durability or not) my sapphire sword, and my silver coins (i don't remember how many) I'm going to post a screenshot of the tool's current state. If this issue could be fixed, that'd be great. thanks! -Mrminesheeps
While not really addressing that issue (crashing cause of the tool), that warning is from iguana's tinker tweaks, and usually happens when the mod updates. However, i've noticed that on a few tinkers tools on the ferret business, so i think something is a little off with the configs. If it's an up to date version of the mod it may be worth sending a bug report to the mod creator.
They removed a mod which allowed you to put parts in tools. Therefore causing issues when the mod was removed by the modpack author.
