Crash log

When using the Dual Hotbars mod and Inventory Tweaks tries to replace a tool that has just broken, but is in one of the extra 9 hotbar slots, it crashes because it tries to access a slot which is not part of the default 9 hotbar slots, so it crashes with the error:

java.lang.IndexOutOfBoundsException: Index: 39, Size: 36

Just a side note, the way the extra 9 hotbar slots from Dual Hotbars works it that it just displays the top 9 normal inventory slots as hotbars slots and allows tools/blocks/items to work the same way as if they were in a normal hotbar slot.

See #216
Don't use replace with mods that mess with hotbars in that specific way, it won't work.
