Humm, your teleporting problem might be the result of some super nasty "rubberbanding", which means shooting back to a previous location after running away from it, usually the result of some nasty lag. I personally have had few problems with Technic, but possibly you are having problems with it and need to switch to vanilla. If you are not using Technic, I recommend trying it out at
hc.to/Launcher.
As for your resource pack problem, I have that time to time. To disable the resource pack, hit the Herocraft icon on your multiplayer screen, click edit, then switch over Resource Packs to disabled. Then run out to a calm area with little complex things, then try to enable the pack. This way it can allow a more easier download on the servers part. If this still fails you, you can always use your own pack/ vanilla, or download the Conquest texture pack on your game itself at

Good luck, and Happy Herocrafting!
