There is nowhere the info that new saves are put in "_LOCAL_" folder and we need to copy paste our save games there.
Found a bug: running an old save, Kana got another weapon slot to use (4 instead of 3).
As for fixes, there is still tooltip flicker in beta. Perhaps you could implement a fix like this (https://www.nexusmods.com/pillarsofeternity/mods/187)
I aslo noticed flickering mouse cursor as well. For me problem occurs when using gsync and framerate is higher than monitor refresh rate. I solved it but limiting framerate.
