I was loading some of my existing saves I use for playtesting and I noticed the time read NaN:NaN:NaN after installing Accurate Playtime (saving the old save and then loading will fix but reset at 0:00) but it works correctly with new saves. Some plugins do seem to have some odd behavior with existing saves (i.e., made before the plugin) for example, TAA_BookMenu may not work with old saves and Felskis autosave may not allow saving at least with Yanfly's Save Core.
Also I was messing around in YEP_Options and thought of making my own custom options using Javascript and Olivia's MetaControls plugin to revamp the quests so a player can toggle between pressing a button/manually viewing the quest (an idea I suggested in a previous comment) or autoviewing the quest like in Lawmage Academy. If you have saw part 5 of my video, you may have saw a Quest Autoview option. Hopefully I may join the LA Discord server since Discord would be more easier to discuss things (like code or achievements) than using itch.io's comments.
