Unions don't really help if you have slow internet. Unions are dependent on your internet.
When a union is made, lets say 5 bricks into 1 union. When you union them together, it appears to be 1 brick, but it actually used a variation of ":remove()" which doesn't get rid of any bricks, so there is 1 brick rendered, and 5 bricks in the memory of the game. |
