Hotseat changes campaign difficulty

[benczeb90]

I noticed that when playing a local hotseat, the human players except for the first human faction, get "Game difficulty: Normal" scrolls upon their respective Turn 1. (I chose Hard campaign difficulty when starting the multiplayer campaign).
Also, changing the faction capitals cost exactly zero money so I can't check what difficulty I'm actually on.

Found it out by having a way too easy multiplayer campaign with the 2nd and the 3rd faction. Got money I couldnot spend, which is totally not what I wanted. (Byzantium, Hungary) The first faction had it noticeably worse, as intended for a Hard campaign. (Poland)

[hotseat]
turns = 0
scroll = 0
autoresolve_battles = 0
disable_console = 0
save_prefs = 1
update_ai_camera = 1
validate_diplomacy = 1
autosave = 0
save_config = 0
close_after_save = 0
gamename = hotseat
validate_data = 1
allow_validation_failures = 1

Obviously I'd want the same difficulty setting for every faction. Can this be solved somehow? Thanks.
