"Mod minecolonies requires structurize 0.13.96-ALPHA currently, structurize is 0.13.108-Alpha

Actually, you should update MineColonies. If your version of mcol needs 96 alpha, it's very out of date. We recommend getting the latest alpha in all cases. (Downgrade Structurize to 104 though, the version of minecolonies that goes with 108 isn't out yet.)

Downgrade to the right version
