Disconnect on "Giant Beetle Lair" enter

As the title says, the Blader and Mage classes, who get instance quests in Desert Scream, have started to have a problem when entering the Giant Beetle Lair.
No errors or anything, just cuts off.

This is after I unpacked an updated repack, but I don't know how to check which files are for Desert Scream/Giant Beetle Lair. Before the update, it did work pretty much fine.

Could somebody please tell me what files reflect what I need to change/restore?
Thanks!

u'r using QuestDungeon.scp from Loca's release, right?

try this:

QuestDungeon.7z - Speedy Share - upload your files here

Thanks... but why do people have to use the most odd-*** sites, that require signups? -_-

I guess I'll try to sign up and download it later...
I already downgraded back down to the 2.81 release for the holiday, will probably upgrade it after Christmas,
as I have to work on other projects on my site, such as a DDR and cosplay section, still...
