I have a question: was playing some map with A LOT of hidden events, using safe sod mod then I got tired to save each step because of hidden events. So I figured out an option for SoD mod to show events:

This is done by replacing mithril mine graphic with the event graphics -as wog graphics will not be used with safe sod. So far so good, is passable and ok. BUT now:

Is there any idea on how this graphic can be deleted once the event was triggered? As the square has no yellow trigger I can't delete it with UN:O. Then type 26 (event) is not recognized by erm -we can only place it, debug doesn't work so how to get if hero steps in or away an event whose position is not known in advance?! Thanks for suggestions.
