- You can no longer teleport to party members who are in the Twilight Strand in Act 1.
- Fixed a bug that prevented teleporting to a party member when you should have been able to.
- Fixed a bug where some Legacy versions of items displayed higher Chance to Block Spell Damage values than they actually applied.
- Fixed a bug with DX9 where Shadows could not be disabled.
- Fixed a client crash that could occur when re-entering the Doedre, Lunaris and Solaris, and Kitava encounters, or any area where Lightning Spire Trap was used.
- Fixed a client crash that occurred in the Piety encounter in Act 3.
- Fixed a client crash that could occur when using Vaal Double Strike.
- Fixed an instance crash that could occur when leveling up various skill gems.
This hotfix has been applied without a restart. Restarting your client and updating will be needed for some of the fixes to apply.
