When I enable Thermal expansion recipes my world will not load, I just get kicked back to the menu screen.

RecipeSets {
# If true, MFR will register its EnderIO-based recipes.
B:EnderIO=false

# If true, MFR will register its Thermal Expansion-based recipes.
B:ThermalExpansion=true

# If true, MFR will register its standard (vanilla-item-only) recipes.
B:Vanilla=false

The only time I can get into any world using MFR and Thermal dynamics, foundation and, expansion is when I have Vanilla only set to "true"

Any suggestions?
