Sheets only produce 2 floor tiles each instead of 4

[Greentryst]

Actions Performed:

1. Use sheets of any material.
   • The sheets will function identically whether they were pre-existing in the map or manufactured by a player.
2. In the resulting dialog box, select the x4 Floor Tile option.
   
3. Enter the desired number of sheets to consume for this purpose.
   • The stated minimum of 2 is not enforced, nor has it been for as long as I can remember. (Why 2 and not 1, anyways?)
     
   • If a number greater than the size of the stack is specified, the number will be reduced to the actual size of the stack, as intended.
     
   • If a number greater than the stated maximum of 20 is specified, the number will be reduced to 20, as intended.

Expected Result: The number of sheets specified, x, will be consumed. The player will assemble 4x floor tiles of the source material.
Actual Result: The number of sheets specified, x, will be consumed. The player will assemble 2x floor tiles of the source material.

Conditions to Reproduce: None. This action may be performed at any time, and repeated, with the same result.

I swore I would fix this 15 times already. I'm a terrible person.

I just fixed this on my local. Expect it to be committed sometime in like 12 hours.

I also would like to mention that I love this bug report and everyone should do bug reports like this.
