onRefreshFileNamesCache();
 

Something along these lines would be very useful. For example, I'm using a clientsided cache for item data that stores information in a .txt file in the client's Graal folder. The first time data is stored and the file is created, Graal doesn't recognize the existence of that file until the client restarts the game. If I at that point could force a refresh of it, it would allow the script to continue to function normally instead of having to wait for the client to restart.

Another example is the problem with players seeing all tiles as completely black the first time they logon a server far too often, due to the game not recognizing the location of the tile graphics.

FILENAMESCACHE.txt only causes troubles really. Either allow it to be manually refreshed by script, or change the way it currently functions, please.

happened to me when i loged on maloria.

I've also had problems with some ganis acting funky when first downloaded. Probably tied to the same issue.

Since Stefan appears to be posting a lot more recently, this deserves a bump.

The problems with tiles is entirely too annoying, imho this should've been done ages ago.

I approve (though it should be refreshFileNamesCache as on should be reserved for events).
