I received this funny looking message while killing Styrax in the Forgotten Pools. Screenshot of the message included. No idea what :16be78f55ba229ae: is other than the exact code for an AE or Effect.
":d74790f54dcf820feposits Allowed" ":d74790f5f1205f18:Withdrawls Forbidden" Virtually every text string in the game has an 8 byte unique identifier associated with it (browse your UI files next time you get bored). Sometimes they leak into view. I've always assumed they served as unique ids for the purpose of NLS support. The text may be different in each translation of the game (English, Russian, etc..) - but the unique id stays the same. But that's just a guess what it's for, the UI modders might know, as that's where it's most commonly seen...
