Thank you Horrorscope for the detailed explanation. I will double check to verify that status effects get cleared after battle.
However, if I avoid a trap with my main character, the 3 others following along are liable to walk right into it, sometimes taking an entirely different route due to the path finding, stumbling into other traps. Then they die or the entire party wipes in a matter of seconds. This has not been fixed. It happened to me several times yesterday under Cyseal. The only solution was to micro manage the movement of each character.
I am running the latest version of the game.
