[SUPPORT] Advanced Turn Based Tile Toolkit

Do you mean preventing units from moving diagonally? Uncheck bAllowDiagonalMovement in BP_GridManager.

I believe there is only one of these in each Turn Manager. You just need to replace it in whatever turn manager you are using.

I tried to follow your exact specifications, down to the specific tile location of units and unit activation order. I might have missed something, of course. Let me know if the issue persists.
