Nether portals problem/bug

Server Specs:

• OS: Win 7
• Ram 8GB
• Processor: 6x3.4Ghz
• java: 1.6.0_26
• Cmd: java -Xincgc -Xmx3G -jar craftbukkit.jar nogui
• Bukkit Version: 1240 (mc1.8.1)
• Plugins: dynmap(v0.22.1), CraftProxy (v124), PermissionsBukkit (v1.2), SuperPermsBridge (v1.2)
• Map runs on a 256MB RAMDisk

Problem:

• Whenever we teleport back from the nether, we always end up back at the original Overworld portal. Thus we cannot take advantage of the quick travel over long distances in the Overworld. The Overworld to nether portal maps correctly but not the other way around

Expected outcome:

• Teleporting from Overworld portal (n) should teleport you to Nether portal (n).
• Teleporting from Nether portal (n) should teleport you to Overworld portal (n).

Produced Outcome:

• Teleporting from overworld portal (n) teleports you to nether portal (n).
• Teleporting from nether portal (n) teleports you to overworld portal (1).
