Did killing the Shriekers get Gareth's response to change?
I'll check if that typo has been fixed, and create a bug report for it if not.

That is a known issue with the mysterious tech switch, if the character does not have a source point. If you freed him earlier, Whithermoore should show up to help if you don't have a source point, but a different issue will prevent that.
Source pools were removed from act 1 a few updates ago, but there are some in later acts. IIRC the number of charges that purging wands have was increased the last update.

Does Loshe have a problem if you load a save in single player?
For the historian, create a blood pool (Blood Rain) and Cast Bless on that.
A couple people reported that lag on the Lady Vengeance. One said they reloaded a save after the fight with Alexander and headed to the ship again, and didn't have a problem the second time.

Did you try saving and reloading? There is a fairly rare issue where a character can become stuck (usually entering combat) with a greyed out skillbar, which that will fix. In co-op, reassigning the character to a different player and back again can also help.
If this happens again, please email a save made when it first occurs (or a Dropbox or Google drive link, etc) to supportdos2@larian.com, with a brief description of which character was stuck and what was happening when it started (entering combat, etc). Even better would be a save before it occurs, with a way (at least semi-reliably) to reproduce it, but so far nobody has reported a way to deliberately trigger this problem. Loading the saves fixes the problem, but at least having information about the state of everything when the bug occurred could help in tracking down the cause.
Each save is a folder in the '..\Documents\Larian Studios\Divinity Original Sin 2\PlayerProfiles\<ProfileName>\Savegames' folder. In Windows Explorer you can zip a file or folder by right clicking on it/them and selecting 'Send To | Compressed (zipped) Folder'.
