My server always crashs and it can not start a signle time because of the version of forge (28.0.93) which is not compatible to my world. When i tested my world in single player, it worked with older version than version 28.0.93 such as 28.0.91. However, in aternos i can't change the version to 28.0.91. It shows only the version 28.0.93 and older versions from 1.14.3 and below.
I suggest Aternos should upload all forge versions in every single minecraft version 1.14.4, 1,14.3,1.14.2,... and so on. It makes a lot easier to choose the forge version that is compatible with player's own world.
