When my party (Ifan, Fane, Lohse and Red Prince) get the yellow Exclamation Point indicator, if I initiate dialogue while controlling Ifan, the dialogue never loads. I get stuck with the dialogue box open, but blank. I'm not able to end dialogue, either, so I am stuck exiting the game and reloading my save.

Has anyone else encountered this, and if so, were you able to fix it? Larian, if you see this, please fix it!

Could you put the savegame with which you have this problem online somewhere? You can find the savegames in Documents\Larian Studios\Divinity Original Sin 2 Definitive Edition\PlayerProfiles\<Profile Name>\Savegames\Story. Alternatively, contact Larian Support (https://larian.com/suipport) and send them the savegame. And are you using any mods?

No mods. I've uploaded my savegame to here: https://www.dropbox.com/sh/yjj32dg2paf6ha4/AABaMR4aTWRoZYeld8SX_vbEa?dl=0

I'll also email the files to Larian, per your suggestion.

This issue is being reported by some users on the Steampowered forums as well.

This should be fixed in the currently available version. Thanks for reporting.
