My forge server with custom modpack launches and runs just fine, but commands are directly being reset, biomes and mobs from mods dont spawn and it is not possible to use/drop/place any items from mods. Vanilla features appear to work fine, it is possible to hit vanilla mobs and place/destroy blocks. Google and other fora didn't turn up anything relevant. Everything works perfectly in the singleplayer Forge client.
Mods installed. There is no chronological order, since I copied them all at once from my client directory. Every mod was installed by simply placing the .jar/.zip in the mods directory, except for the 'Flan's mod' source packs, which had to be placed in a separate map called 'Flan' in .minecraft.
