Trigger delay, not working in procedural dungeons

If you put a delay in a function for example, Finish Dungeon and the trigger is the Death of a Mob, it doesnt work after map save or reload of the plugin, restart etc, because the delay setting is not saved on file. If you create the function, leave the dungeon and play instantly it works, but only that time then it doesnt...

I tested on several triggers and it's the same..

Probably there are more issues related to file saving...
