No i'm doing them all at the quests at the same time to avoid going back and forth on maps. Do i need to complete quests in a certain way? If some quests require you to finish other quests first i think that those quests that have prerequisites should be disabled while the required quests are not yet completed.
In this particular case, the needed item requires that you advance the other quest first to get it.
quest reminder feature was working but after running a few missions it suddenly disappeared i have tried changing to different quests reloading a different save and using the bug fixer in the sleeping chamber but nothing seems to fix it.
the only thing that brings it back is start a new game and i dont want to do that
You could check if the quest box is disabled in the menu for some reason, or try to enter and leave the CG room, as there is a "hide" function that makes the box disappear while you're in the menu and replay of scenes.
Since the issue is not in a new game, it means that something in your save happened that caused the box to be marked as hidden, but I can't say what exactly the problem is in your case.
If both of these option don't work for you, you could give me the .rpgsave file from the www/save folder with the save slot number in which you have the issue, so that I can take a look if I can find the problem.
