This is an account-specific bug that is affecting one of my guild members. This bug is causing major problems in guild war, as nearly all attacks vs Vulture result in timeouts because Vulture will not drop as expected.
I have recommended to this person to try the steps outlined by @Vampaerus in another post in case there is a problem with the app client's assets, however, he's lost accounts before and is nervous about reinstalling and losing accounts again (he plays multiple servers).
@DSKenshirou_X @Riverwitch_IV @Princess_Ertreya have you heard anything about this issue?
Working on getting video evidence, in the meantime I wanted to bring it to everyone's attention to see if anyone else has encountered a similar issue.
