Hi Baratorch, I'd like to report two issues of the latest HD+ERA here.
They have been reported by me before, but it seems my reports were confusing and you probably didn't get the idea. Here I'd try again with detailed explanations.
Note that these issues were non-existent in 5.2 RC11. They started only from some versions between 5.2 RC12 and RC15.
They are really worth fixing IMHO

1. WoG dialogues disappear immediately after showing with any OpenGL mode.
Try to save wog options and you will see. The dialogue pops up and vanishes quickly.
This happens for all wog dialogues.

2. Loading in battle initiated by AI players (attacked by AI) results in an infinite loop.
ERA debug+save
To reproduce this bug, you need to
1) Load my save (or create any condition for AI to fight you)
2) End turn and wait for AI to attack you
3) Try to Load in battle
4) Here you are )

Once again, these issue happens since some versions between 5.2 RC12 and RC15, so you only need to check changes from these versions. Thank you for improving the support with ERA!
