@HobbitPower fixed problem with barriers and included a screenshot

Hello, I have several comments:

• The poorly defined barrier between the two teams: 1 block too many on each side.
• There's air under some of the blocks, even if this is possible in a mine, I doubt it's deliberate on your part.
• The ores are poorly distributed between the 2 teams (iron, coal).
• There's a wall under the map

@farooqkz As TMR pointed out:

• Team zones need an update. You get teleported back while standing at the red barrier.

• The ores are fine, there is just a huge difference for the coal. You could add some coal blocks, although there should be still enough coal for both sides.

• Replace the stone there with ind barrier glass:

• This can be fixed too. Make sure to check the corner points of the maps then.
