It seems to occur when the addon tries to load a raid on login for me - getting into Mag from a D/C was where i had problems, and it was trying to load group and raid frames on login. Eventually asked to be removed and reinvited once I logged in successfully, which worked. Same issue was happening later with Karazhan, invites were no issue, nor was zoning, but loading from a restart or a logout was absolutely impossible. 3+ min lockups. Ended up disabling the mod.
That's exactly what happened to me (not using Aguf raid frames only player/target/party frames). I can log back in if I'm not in the raid but freeze up when I'm in a raid group, log out and try to get back.
And here comes the embarrassing question: Where/How do I try the branch version vs the one I download from wowace via the updater, or is that the branch version? Happy to load whichever version needs testing tonight and try again.
I had the freezing happen still on the 12th (PVE raid, Magtheridon'slair), with a version current or downloaded via the updater the same afternoon (BST). Apologies but have updated since so I cannot link the exact revision#.
Addons used: Mostly ACE2. Raid/error relevant: Aguf, Sraidframes, Ora2. Not using a standalone library yet so every addon is loaded with externals.
Occasion: Tried to log back into a raid in Magtheridon's lair, after disconnecting (and rebooting). While no changes were made to addons between the dc and the login attempts, my screen froze up completely right after entering the game GUI.. definitely looked like around the time when the unitframes were loaded. Specifically, I saw the party frame come up, then froze. Waited a few minutes, then killed the game process and rebooted. Rinse repeat.
This wasn't resolved until I renamed the 3 addons' lua files (not sure which one caused it so I tackled all 3) and reverted back to Blizzard unit frames and CTRA.
Interestingly enough there were no issues prior to the disconnect. Was raiding through the trash fights just fine. Also, I have not yet experienced these freezes in any other PVE instance, just Magtheridon's lair (two occasions), and only when facing the boss room where everybody prepares for the fight.. maybe it's a buff/sync/display lib related issue as one of my guildies speculated? If I get to raid tonight I'll be able to try the latest version.
Appreciate any work on the addon. It's great. Especially love the built-in combat text as a healer. :)
