I could smell the default "one size fits all" copy/paste response from an admin, coming from a mile away lol. At least you could personalise it, much of it is of no relevance to the issues alice is having!

Alice, the "now exitting Toto-Rak" is what u see when someone clicks the centre of the unlocking device (blue swirly thing), so i expect thats what happened there and unfortunately as you didnt open the chests and pool the loot, its gone for good now ; ;

As far as why your loot dissapeared on exit, i dont have an answer for that one sorry, seems weird.

Ive heard of the issue of people getting stuck on a gate that others can get through after unlocking. The work around seems to be to run a long way back towards the beginning to try to refresh the glitched area that loaded, or try to "return" then run back to your group (this may be more effective and quicker but i cant confirm this as ive not had the issue myself)

all the best alice
