OP should make a new. modded server
I've been looking into mods and testing them, if the modded server comes up vanilla will go down. (Map will be uploaded of course) current mods are:
AdditionalBanners, ArchitectureCraft, AuraCascade, Bagginses(may be removed), Biomes o plenty with Realistic terrain generation (the landscapes are amazing), Buildersguides, Chisel(not 100% sure, seems to be a bit iffy as the diamond chisel texture is broken), Chisel and bits, ComputerCraft, Dark utilities, Durability show, Ender Utilities, Flat colored blocks, Fun ores(more ores because who doesn't like having a stockpile of ingots/blocks?), Gravestone, Hopperducts, Inventory pets, Inv tweaks, IronChest, Just enough items(Not enough items isn't updated yet), Journey map, Lucraft core(Because ores), More furnaces, MrCrayfishFurniture, NeoTech, OpenComputers, Optifine, PaintThis, Pams harvestcraft, Project E(Extremely likely to be removed), RedStonePasteMC, Roguelike Dungeons, SilentsGems, Tinkerers Construct 2, Thaumcraft, Thut Elevators, A mod that adds a key to lock chests, Grapple Hooks, and Waila. These are all in 1.8.9 so the server will be on 1.8.9. If you don't want some of these mods please tell me so i can look at them and determine if they need to stay, there are a good few i'd like to keep because they're neat though so not all requests will be put through. Also if anyone can find a hang glider or simple jetpack mod for 1.8.9 that'd be great.
