Strange bug with drawing level with tilelayers
 

Made a video to better explain it, read my chat in it. Watch in HD!

EDIT: Attached the actual level. If you need to see it online Stefan, you can logon Dev xXziroXx/Maloria and warp to "mal_flyingshiptest.nw"

I noticed right before your Win32 error you got a UAC prompt. Try turning off Desktop Dimming for UAC. The desktop dimming can cause issues with some programs (especially older games). To turn off dimming, move the UAC slider in Windows 7 down 1 tick.

I already did that last night actually. Doesn't really explain Graal wanting to draw weird tiles in the level that shouldn't be there. They don't show up in Gonstruct either, and that weird Win32 Error made the level draw properly in-game.

Update: Not a Graal client bug, but rather a bug with Gonstruct being able to delete sections of the level and not fill it up with a default tile, causing the Graal client to attempt to display a tile that's not defined in the level other then by a blank.

It's fixed in V6 actually, we had a level on Zodiac doing the same thing.
