Class Specific Disconnection Issue

[Agustus]

Hello all, I am having trouble with a very odd disconnection issue, and thought I would pick the brains of those vastly more knowledgeable. I don't wish to say the server, but the dev there has been great in trying to help, but he cannot find or replicate the issue himself.

The issue is this; when I zone my Ranger character into dungeons(CB, Mistmoore, Runnyeye, Unrest, so far tested.) I cannot interact with anything, engage combat, chat, /who commands, and after about 30-45 seconds I get a disconnected message and either bounce back to char select or back to account login page. In outdoor zones and some cities I have no issues.

I am dual boxing and my other character, an enchanter, is just fine, everything running perfectly. This led to much testing, deleting the characters and remaking, making them on different accounts, deleting Titanium client and fresh installs, even tried two different machines Win 10 and Win 7. Tried single boxing the Ranger as well, same fate no matter the change.

It only does this on a Ranger specific character, I have tried almost all classes and they all behave normally except Rangers(of all races/sexes).

Other people including the dev have tested Rangers and they seem to be fine for them.

Sorry for the long winded explanation, but has anyone ever dealt with something like this? Is it a port issue? Client files? Seems so odd to me it's only the Ranger and just in dungeons. Thank you all in advance.
