Removing and adding status conditions

Sometimes status conditions are not applied correctly and sometimes they are not removed, leaving you “poisoned" forever, or “invisible “ forever… ive asked franz to remove the status condition but he says he cant do it, and when you force him to do it he just changes the narration…. Ive found 2 ways to do it manually… 1-go back to the event that caused the status and click the undo button for the chat prompt that notifies you of the condition. This works when the condition is applied normally and is not later removed. The second method took me an hour to figure out. I tried method 1, but when the poisoned status was applied it was not mentioned in the chat prompt, it was supposed to be applied so it didnt matter, but later after combat, long rests, trading etc… i noticed i was still poisoned. Asked franz to remove it and he couldnt, just changed narration… the trick i did was i told him to spawn a 1 hp enemy that he ended up naming “placeholder entity". Rolled for initiative to start the encounter, then asked him to remove the poison status. Worked without a problem, only asked once…. Status conditions can only be applied/removed during an encounter.
