I have been using AMP to host a modded java server, with roughly 100 mods. Due to of these mods, the nether roof height is 192 instead of 128, which makes building large gold farms somewhat difficult. I have tried adjusting the logical and build height of the world withing the mod (Incendium) file. This works correctly ONLY if the world is generated witht the already modified mod file in singleplayer. For the last 5 months we have made a lot of progress on the server, which we do not want to lose. Is there a way to make a new instance that behaves accordingly with the modified world height, while also not losing builds and player data that was made before? If so, how should I port that data to the new instance?
Thank you in advance
