Unexpected tile duplication

[cavrly]

Having 1 stack of any tile will suddenly place more tiles when holding the Place Platform keybind.

The tile initially placed is not accounted for when determining the heldItem's stack.

Platform.cs | class Utils | function Place

        Item heldItem = Main.LocalPlayer.HeldItem;
        . . .
        if(heldItem.stack<=config.PlatformLength) heldItem.stack--; // accounts for the tile initially being placed
        if(isWall && heldItem.stack>config.PlatformLength) heldItem.stack++; // do not know what causes an extra wall to be removed when the stack is greather than config length?
        if(heldItem.stack<=0) return; // the tile initially placed already depleted; why bother placing another one?
        . . .
        for (int n = 0; n < config.PlatformLength; n++)

Adding these lines may fix the issue.
