A couple of bugs I've noticed while playing the Markus Wulfhart Vortex campaign after the Shadow / Blade update.
There is a bug where entering shipwrecks does not trigger any popup selection.
It's sometimes possible to voyage from wreck to wreck (at normal speed) without anything happening.
The bug seems to be reset after reloading the save file.
There was also a bug where Kalara's quest objective regarding the Emerald Pools completed itself after a confederation of Itza by Hexoatl, no interaction by the player, no control over the settlement.
