As in 1.32, also in PTR 1.33 the save/load system seems to still be quite broken.
- Custom UI using the “new” frame natives don’t properly save/load
- Music themes and music lists don’t save/load
- Script initialization is not carried out when loading/saving game. This is an issue for all the actions that require lobby initialization, like for instance overwriting any of the default game UI.
While I have not fully tested this in PTR 1.33, these issues plagued 1.32 and I think they are worth looking into now, while in PTR phase.
