Whenever I log into the mods Zombie Apocalypse, World of Magic, and The Arctic Phoenix, I get logged out after about 8-13 minutes if playing AND it loads really slow when I try to log back in

Thank you for your report!
However, this issue is Invalid.

Unfortunately we don't accept issues related to third party addons here on the bug tracker, but please add more details if you think this also affects multiplayer over Realms, LAN, or XBL.

I'd suggest contacting the addon owner directly or seeking help on the Minecraft forums.
