That doesn't tell us much, you do know there are likely to be many upon many version made for 1.7.10 for both mantle and Tico.1.7.10 mantle and 1.7.10 Tinker Construct
That doesn't tell us much, you do know there are likely to be many upon many version made for 1.7.10 for both mantle and Tico.
In your mod folder the proper version number should be in the mod jars name.
I find that hard to believe as the version of mantle I am using has a lot more then 1.7.10.
My version of mantle is named "Mantle-1.7.10-0.3.2".
The bold underline is the actual version of the mod being used.
Either way, that error you have happens when a core mod is not the right version. You need to upgrade/ downgrade either Mantle or TiCo.
