There is a huge, gamebreaker bug in 2.2.0 version of Gregblock modpack. You can create infinite amount of steam with just 1 fuel. Bronze boiler refuses to consume last fuel in its input hatch. This problem is fixed in 2.2.1 version of the modpack but we can't play because Aternos servers still uses old version of the modpack.
Can you update the modpack to 2.2.1 version please? Thanks!
