I don't know if there have been a solution, but i still regularly get inside the void during a travel, sometime it does not happen and sometime it does, making it very hard to understand why it is happening.
And once i am in the void i can't do anything other than reloading a previous save, because of the 2nd problem that prevent me to just use the classic daggerfall travel :
Even if i disable "player controlled cautious travel" so at least i could just switch to Cautious to get the game teleporting me at destination as in classic type of travel :
Ingame i still am forced with the player controlled travel :
I'm using the latest version of Travel Options with the latest 1.4.4 Daggerfall Unity, though i have no idea if another mods (as i use several) could be responsible.
EDIT : i found the source of the problem :
You don't get the classic travel when selecting "cautiously" if you try to travel to a wilderness location, you only get the cautious "classic" travel if you travel to a defined location (dungeon, town, etc...).
So i guess it becomes a suggestion : allow cautious "classic" travel if you just want to travel to a wilderness place .
